12/22/16 - IEM Director Bin He and Research Team Made Breakthrough in Mind-Controlled Robotic Arm
A first-of-its-kind mind-controlled robotic arm that utilizes technology developed by Dr. Bin He, Professor of Biomedical Engineering and director of IEM and the Center for Neuroengineering (CNE), was featured by a variety of media including the Wall Street Journal, Star Tribune, Fox News, and KSTP. "This is the first time in the world that people can operate a robotic arm to reach and grasp objects in a complex 3-D environment using only their thoughts without a brain implant," says Dr. He. Building upon technology Dr. He developed for mind-controlled drones, the robotic arm system is a big step toward a future of medical applications that could range from rehabilitating stroke patients to helping paralyzed patients regain the ability to perform basic tasks in their everyday lives. The paper was published in Scientific Reports, a Nature research journal.

12/22/16 - Blood Washing Device Invented by Allison Hubel is Featured by Twin Cities Business
A blood washing device invented by IEM Executive Committee Member Dr. Allison Hubel, Professor of Mechanical Engineering, and Director of the IEM-affiliated Biopreservation Core Resource (BioCoR), was featured by Twin Cities Business. The automated system cleanses from thawed blood glycerol preservatives, which are added to blood prior to its freezing for storage, and it does so more efficiently and safely than does a centrifuge, which has been the standard type of equipment used for this process and which requires more time and labor to use and results in high cell losses. Dr. Hubel's device could ultimately help to make large strategic reserves available from blood produced from stem cells, during emergencies when insufficient quantities of donated blood are available - something which is not as possible with centrifuges. The device took a big step toward this future with a $223,000 Phase I NIH SBIR grant awarded in September to the start-up company seeking to commercialize it, Headwaters Innovation Inc., led by a successful local entrepreneur.

12/22/16 - Henry Balfour Discusses Epstein-Barr Virus with USA Today
IEM Member Dr. Henry H. Balfour, Jr., Professor of Laboratory Medicine and Pathology, was interviewed by the USA Today about Epstein-Barr Virus (EBV), commonly-known as mono and "childhood kissing disease." Dr. Balfour says that the disease can potentially have long-term consequences for those who suffer from it, including the 280,000 college freshmen that contract the disease, annually. "Epstein-Barr Virus is responsible for a number of chronic conditions, especially certain forms of cancer and autoimmune disease and even multiple sclerosis," says Dr. Balfour. Symptoms of the disease experienced later in life can include symptoms of the flu that don't completely subside, joint pain and ringing in the ears, according to Dr. Balfour, who adds that the EBV virus can also lead to chronic fatigue and fibromyalgia. Dr. Balfour, who's research is focused on the development of a vaccine against EBV, says that "the best way to deal with all these EBV diseases is to prevent them from happening in the first place."

12/22/16 - Kelvin Lim Discusses Use of Ecstasy to Treat PTSD with KARE 11
Dr. Kelvin O. Lim, Professor of Psychiatry, Drs. T.J. and Ella M. Arneson Land Grant Chair in Human Behavior and Co-Chair of IEM's Neuroengineering Theme was interviewed by KARE 11 about new, FDA-approved Phase III clinical trials of the party drug Ecstasy (MDMA) for the treatment of PTSD. MDMA is classified as a Schedule 1 drug with no currently accepted medical use. The new trials build upon research that included a trial in which MDMA was used as part of a broader treatment regimen, including therapy, that resulted in a 56% decrease in the severity of symptoms of PTSD and two-thirds of the patients no longer meeting the criteria for having the disorder. Dr. Lim, who has not studied MDMA, says that the potential use of MDMA to treat PTSD is "very promising and exciting" due to the lack of effective medications and that "thirty to forty percent of people don't respond to treatment". However, Dr. Lim cautions that if MDMA is approved as treatment for PTSD, mechanisms will need to be put in place to insure that it used in a safe and effective manner.

12/22/16 - Melena Bellin Discusses with Reuters Health Testing to Predict Insulin Dependence Following Total Pancreatectomy with Islet Autotransplantation
Dr. Melena D. Bellin, Associate Professor of Pediatrics, discussed with Reuters Health the results of a study suggesting that the Lower Oral Glucose Tolerance Test (OGTT) can help to predict the insulin dependence of chronic pancreatitis patients following total pancreatectomy with islet autotransplantation (TPIAT). The research showed a relationship between patients' glucose status prior to the procedure, as measured by OGTT, and the need for insulin therapy one year after the procedure. "While risk of diabetes is most often a secondary consideration (to pain control/quality of life) in selecting patients for TPIAT, it is very important that patients are provided a realistic expectation of outcomes in preoperative counseling," says Dr. Bellin, who adds that "Some patients may choose not to undergo TPIAT knowing that their testing before surgery puts them at very high risk for lifelong insulin dependence after surgery."
OGTT Testing May Help Counsel Patients Before Total Pancreatectomy with Islet Autotransplantation

11/28/16 - IEM Industrial Advisory Board Member Among Brain-Computer Interface Investigators Published in New England Journal of Medicine
IEM Industrial Advisory Board Member Dr. Timothy Denison, Vice President of Research and Core Technology, and Technical Fellow at Medtronic, was among investigators whose research, on the use of a fully-implanted brain-computer interface (BCI) for communication by an ALS patient, was published in the New England Journal of Medicine. The patient suffers from "locked-in syndrome," a form of paralysis which prevents her from being able to communicate verbally or in other muscular-based ways, but which does not affect her cognitive ability. By thinking about moving her fingers, the patient generates a brain signal that is identified and converted into a mouse click by the BCI system, allowing her to then select individual letters on a keyboard and type messages. Dr. Denison says that the next objectives are to make the technology operate faster and useable in a home environment. The research was performed at the University Medical Center (UMC) Utrecht, in the Netherlands, and was funded, in-part, by Medtronic.

11/28/16 - Theresa Reineke Leads Team that Discovers Method to Improve Effectiveness of Orally-Taken Medications
IEM Member Dr. Theresa M. Reineke, Professor of Chemistry, led a team of researchers who, along with colleagues at the Dow Chemical Company, discovered a method of customizing ingredients to make orally-taken medications more dissolvable, and thus absorbed in the bloodstream more quickly and effectively than existing methods. The team tested the process with an anti-seizure drug and another that treats late-stage prostate cancer. Dr. Reineke says that the method could be broadly applied "by many companies to create other life-saving medicines." The research has been published in the American Chemical Society's ACS Central Science and a patent on the technology has been applied for by the University of Minnesota and Dow. The study's Co-Author, Dr. Frank Bates, a University of Minnesota Regents Professor of Chemical Engineering and Materials Science, says that this breakthrough is "a perfect example of what can happen when industry and academia come together."
New Discovery Could Help Oral Medicines Work Better
11/28/16 - Jerrold Vitek Discusses Innovative Deep Brain Stimulation Procedure to Treat Neurological Disorder
IEM Member Dr. Jerrold L. Vitek, McKnight Professor and Chair of the Department of Neurology, discussed in a November 5th Star Tribune article the progress and potential of Deep Brain Stimulation (DBS) to help patients struggling with a variety of neurological disorders, such as Parkinson's Disease (PD). The research uses a method called "closed-loop stimulation" in its DBS procedures, which triggers pulses only when abnormal neural patterns are recognized. This new method also has the potential to reduce post-surgery side effects, such as headaches and dizziness. "This [procedure] has already gone far beyond what anyone thought it could be," said Dr. Vitek. "But we believe that we can fine-tune this even more, so people can have a much better quality of life." Dr. Vitek and his colleagues are also seeking to develop a novel pattern of stimulation called coordinated reset that he says "is a very new and exciting approach." Both closed-loop stimulation and "coordinated reset" "are novel and will provide additional benefits for patients with PD who undergo DBS," says Dr. Vitek.

11/28/16 - Daniel Duprez Discusses Complexity of Relationship Between Diet and Cardiovascular Health
IEM Member Dr. Daniel Duprez, Professor of Medicine, Donald and Patricia Garofalo Chair in Preventive Cardiology, was featured in an article in the October edition of Minnesota Monthly, "Rethinking Conventional Wisdom on Heart Disease." Focusing on research about the relationship between a person's diet and cardiovascular disease, the article described the recent discussion regarding a heart-healthy diet. There are controversial reports that eating more meat and butter would not cause heart disease in everybody. In contrast, studies of the Mediterranean diet have clearly shown that eating more healthy fats from fish, nuts and vegetable oils decreases risk for heart disease. In addition, recent studies show that replacing fats with higher amounts of starches and sugars actually increases the risk of heart disease, which goes against thinking that evolved, in large part, from a study funded by the sugar industry in 1967. "Is it not time to pay more attention what we eat and how we eat, instead of using only drive-in and micro-wave prepared frozen food or canned food with a high sugar drink and dessert? Healthy eating is the corner stone of prevention," says Dr. Duprez.

11/28/16 - Kathryn Cullen Utilizing Brain Imaging to Study Non-Suicidal Self Injury in Adolescent Girls
IEM Member Dr. Kathryn Cullen, Assistant Professor and Division Chief, Child & Adolescent Psychiatry, Department of Psychiatry, and colleagues are beginning a 5-year study that will examine the relationship between self-harm behavior and certain biological metrics, such as hormones and neurocircuitry, in adolescent girls. The number of these non-suicidal self-injury (NSSI) behaviors has been on the rise in recent years, due in part to the diffusion of these behaviors over social media networks. Citing the current lack of data for biological factors as a cause of NSSI behaviors, Dr. Cullen is seeking to find evidence linking the two, stating, "We hope to uncover a meaningful understanding of the neural mechanisms driving NSSI, paving the way for developing new treatments to address NSSI." Besides linking these factors to NSSI, Dr. Cullen hopes that this type of research will help reduce the stigma around mental illness, providing people with a new lens through which they can understand these afflictions.
Emerging Methodology May Improve Mental Health Research
11/28/16 - Alan T. Hirsch & AHA Request CMS Coverage for Supervised Exercise Therapy for Peripheral Artery Disease
IEM Member, Dr. Alan T. Hirsch, Professor of Medicine, Epidemiology and Community Health, Director of the Vascular Medicine Program, and Co-Director of the Minnesota Heart Health Program, on behalf of the American Heart Association (AHA), has requested coverage from the Centers for Medicare and Medicaid (CMS) to provide all Americans with access to supervised exercise therapy as a first line treatment for peripheral artery disease (PAD). For the more than 8 million people who suffer from PAD in the U.S., leg artery blockages lower the flow of oxygenated blood to the legs resulting in muscle fatigue, discomfort and pain during exercise, a symptom called "claudication". People with PAD also face a very high short-term risk of heart attack and stroke.
Currently, claudication is commonly treated via invasive procedures, such as stenting or surgery. However, supervised exercise is now recognized as one of the most safe, effective and inexpensive treatments to improve claudication, in part due to a large NIH-supported trial completed by Dr. Hirsch and other University of Minnesota faculty. The exercise setting also lowers cardiovascular risk. "Stenting and medication will continue to be a common way to treat PAD and these approaches may be preferred by some patients," Dr. Hirsch said. "But now we can offer a program that offers all patients a more therapeutic choice."

10/27/16 - IEM Member & Colleagues Discover Cause of Resistance to Breast Cancer Drug
IEM Member Dr. Douglas Yee, Professor of Medicine and Pharmacology and Director of the Masonic Cancer Center, in collaboration with Reuben S. Harris, Professor of Biochemistry, Molecular Biology and Biophysics, and their colleagues, have identified a protein, APOBEC3B, that creates mutations leading to resistance to the breast cancer drug tamoxifen. As reported in Health Medicine Network, the discovery could lead to improvements that would make tamoxifen more effective in treating breast cancer and also to the treatment of other cancers that become drug-resistant. "In the treatment of all metastatic cancer, patients will eventually develop resistance and progress. What are the mechanisms of resistance? [APOBEC3B] is proving to be a major driver of resistance and something we're continuing to actively investigate," says Dr. Yee. The results have been published in the journal Science Advances.
Culprit Found in Breast Cancer Resistance to Tamoxifen
10/27/16 - FDA Approves New Epilepsy Drug Developed by College of Pharmacy Faculty
IEM Member Dr. James Cloyd, Professor of Experimental and Clinical Pharmacology, and Director of the Center for Orphan Drug Research, and his departmental colleagues, Drs. Angela Birnbaum and Ilo Leppik, have developed a new epilepsy drug product that received FDA approval on October 8. As reported in Epilepsy News Today, the drug, named Carnexiv, can be injected, making it an alternative when patients are unable to take the oral carbamazepine formulations, as may occur when a patient is unconscious or has a severe gastrointestinal disorder. "This approval is the result of years of work to create a novel and stable injection formulation to support patients who need an alternative to oral carbamazepine," says Dr. Cloyd. Carnexiv's development began with NIH funding (Leppik, PI; Cloyd, Co-PI) that resulted in the publication of a pharmacokinetic study. The study laid the groundwork for the design of a Phase II trial that was used as part of the NDA. Development continued through a partnership between the University of Minnesota and a drug company, Lundbeck. A key element in the development plan was submission of an orphan drug designation application (Cloyd co-author) to the FDA, which granted Carnexiv orphan drug status in 2013.

10/27/16 - IEM Members Part of Team that Discovers Role of Endoglin During Embryonic Development of Cardiac & Blood Cells
IEM Members Dr. Rita Perlingeiro, Professor of Medicine/Cardiology, Dr. Daniel J. Garry, Professor of Medicine, and Dr. Naoko Koyano-Nakagawa, Assistant Professor of Medicine/Cardiology, are a part of a team of researchers who discovered the role endoglin plays in the development of the blood and cardiac cells during embryonic development. These researchers and their colleagues manipulated primary heart cells from zebrafish and mice and differentiated mouse pluripotent stem cells to identify the effects of endoglin on cellular expression. Dr. Perlingeiro says that "by using multiple model systems, combined with specialized cell sorting technology and sequencing tools, our findings help uncover mechanisms previously unseen in the few cells engaged in these early development decisions." This research may provide further information in the roles that endoglin plays in congenital heart defects, as well as discovering ways to catalyze the development of blood or heart tissue following an injury.

10/27/16 - IEM Team Begins Researching Application of 3D Printed Scaffold to Treatment of Spinal Cord Injuries
A team of IEM members, Dr. Michael McAlpine, Benjamin Mayhugh Associate Professor in Mechanical Engineering, Dr. James R. Dutton, Research Assistant Professor of Genetics, Cell Biology, and Development at the Minnesota Stem Cell Institute, and Dr. Ann M. Parr, Assistant Professor of Neurosurgery, is working on a new research project that is using 3D printing to construct a scaffold to support cells in the reconstruction of an injured spinal cord. Though in the early stages of development, the team hopes to create a technology that will "provide an effective therapy for spinal cord injury," says Dr. Parr, essentially a "spinal cord on a chip." The scaffold could potentially be used to treat patients with chronic spinal cord injuries and may lead to other advances in the field of regenerative medicine.

10/27/16 - Ben Hackel Close to Commercializing Unique Molecular Imaging Probe for Cancer Detection; MN-REACH Funding Playing Key Role
IEM Member Dr. Benjamin J. Hackel, Assistant Professor of Chemical Engineering and Materials Science, has developed a molecular imaging probe detectable by PET scans for the imaging of numerous types of cancers, including colorectal and breast cancers. As reported in Twin Cities Business, the probe can improve how these cancers are treated. "It's a way of identifying which patients are likely to respond to a particular type of therapy versus patients who aren't likely to respond - it's a personalized medicine approach. Clinics right now don't have a very good way of differentiating between these two patient populations, so we propose that a PET imaging approach would be able to provide that," says Dr. Hackel. MN-REACH funding is being used to complete the final steps toward commercializing the technology, including "making some small but important modifications in the molecule so that it will perform more effectively at the human patient level," according to Dr. Hackel.

10/27/16 - David Jacobs is Lead Author in Study Published in the Journal of Pediatrics on Future Benefits of Healthy Eating by Teens
IEM Member Dr. David R. Jacobs, Professor of Epidemiology & Community Health, was the lead author of a study published in the Journal of Pediatrics showing that healthy eating by teenagers leads to less weight gain and BMI during early adulthood. The study, which followed more than 2,500 students at Minneapolis and St. Paul high schools, from when they were 15 years old until they were 25, showed that the benefits were experienced by not only those who had healthy diets at age 15 but also by those who switched to a healthy diet during those years. Dr. Jacobs concludes that "food preferences and attitudes may be established as early as age 15," and that the "choices adolescents make during that stage establish a lifetime diet pattern, which could influence weight gain over time."
Higher Quality Diet in Adolescence and Dietary Improvements Are Related to Less Weight Gain During the Transition from Adolescence to Adulthood
09/30/16 - Jerry Vitek and Colleagues Awarded $9 Million Udall Center of Excellence in Parkinson's Disease Research
A recently-awarded Udall Center of Excellence in Parkinson's Disease Research at the University of Minnesota will be led by IEM member Dr. Jerrold L. Vitek, Professor and Chair of the Department of Neurology. It is one of 9 such centers funded in the U.S., and will be supported with more than $9 Million of NIH funding over 5 years, with its research theme being "Circuit-based deep brain stimulation for Parkinson's disease." Dr. Vitek, who will serve as the center's Principal Investigator, says that the University of Minnesota has "a world-class multidisciplinary team to treat patients with Parkinson's disease, and because of our significant experience and expertise we are able to take on this complex and often debilitating movement disorder with a goal of improving patient's lives." Legislative support through the MnDRIVE Brain Conditions initiative played a key role in securing the center award for the University, according to Dr. Vitek. Two IEM Seed Group Grants also helped to facilitate the early development of the center's research.

09/30/16 - Wei Chen and Colleagues Awarded $4.4 Million NIH BRAIN Initiative Grant
IEM Executive Committee Member Dr. Wei Chen, Professor of Radiology, and his colleagues were recently awarded a five year, $4.4 Million NIH BRAIN Initiative grant for research entitled "Integrated FMRI Methods to Study Neurophysiology and Circuit Dynamics at Laminar and Columnar Level." According to the project's Public Health Relevance Statement, the research aims to show "how the brain functions at the micro-circuit and network levels," which "should lead to transformative breakthroughs in understanding dynamic functions of the human brain, underlying electrophysiology basis and mapping specificity of fMRI to a new level." In addition, it could potentially lead to the development of leading-edge technology that will make possible more safe and effective deep brain stimulation (DBS) devices for patients. This is the second BRAIN Initiative grant that Dr. Chen received from NIH.

09/30/16 - Jonathan Sachs Published in Nature Chemical Biology
Research conducted by IEM Member Dr. Jonathan N. Sachs, Associate Professor of Biomedical Engineering, entitled "Oxidation increases the strength of the methionine-aromatic interaction," has been published in Nature Chemical Biology. The study, says Dr. Sachs, demonstrates "that oxidation increases the thermodynamic strength of interaction between methionine and aromatic residues," and "that this change is sufficient to block ligand binding in a Tumor Necrosis Factor receptor, and to lead to misfolding in a calcium binding protein involved in cardiac function and heart disease." Dr. Sachs says that this new understanding "will open new avenues of therapeutic design in proteins that are vulnerable to age-related oxidative processes, including neurodegenerative diseases like Parkinson's."

09/30/16 - Bob Tranquillo Leads Team that Developments Grow-Able Synthetic Blood Vessel; Could Eventually Treat Children
A research team led by IEM Member Dr. Robert T. Tranquillo, Professor and Department Head of Biomedical Engineering, has developed an implantable blood vessel that could eventually be used to treat children with heart defects. As reported by the Star Tribune, this vessel is unique because it can continue to grow as the child grows, as it did in growing lambs, which would allow children to avoid having to get it replaced later in life with surgeries that are costly and carry a lot of risk. "For the well-being of the patient, and not to mention the cost involved, there could be really major benefits if this material does in fact grow in a human. We've shown it in a sheep, and we would hope that someday it would also be demonstrated in a patient," says Dr. Tranquillo. The vessel could potentially be used to treat more than 1,000 children in the U.S., annually.

09/30/16 - IEM Group Grant Leads to NIH R01 Grant; Promotes Global Diversity
IEM members Dr. Donald Simone and Dr. Kalpna Gupta received a multi-PI NIH RO1 grant to examine novel targets to treat pain in sickle cell disease. Dr. Simone is a Professor, Department Chair and Division Director, Department of Diagnostic and Biological Sciences and Dr. Gupta is a Professor of Medicine and Co-Chair of the IEM Molecular and Cellular Bioengineering Theme. Dr. Gupta says that the research will address a major co-morbidity associated with sickle cell disease, that affects vast populations globally and mostly African-Americans. "We thank the members for promoting the IEM vision of promoting global diversity. Preliminary data for this grant was supported by an IEM Group grant," says Dr. Gupta.
09/30/16 - Christy Haynes Discusses with Chemical & Engineering News Female Chemistry Faculty Advancements at Top Institutions
IEM Executive Committee Member Dr. Christy L. Haynes, Professor and Vice Chair, Department of Chemistry, discussed with Chemical & Engineering News a recent growth trend in female faculty advancement in chemistry departments at leading Ph.D.-granting institutions in the U.S. While female representation among chemistry faculty grew only 2% to 19.1% from 2013-14 to 2014-15, the increase stands out after years of more incremental increases. Dr. Haynes says that the Open Chemistry Collaborative in Diversity Equity (OXIDE), an initiative supported by the NSF, NIH and DOD, has been working to improve these numbers by getting the leaders of these departments, who are mostly white and male, to drive diversification, instead of placing much of this burden on women and minority Ph.D.'s and faculty. "In bringing all the chairs together, they're trying to make sure that all the work to increase diversity doesn't land on the people that are the diversity," says Dr. Haynes.

09/30/16 - Pierre-Francois Van de Moortele & Thomas Henry Awarded NSF CRCNS Grant
IEM Members Dr. Pierre-Francois Van de Moortele, Associate Professor of Radiology CMRR and Dr. Thomas R. Henry, Professor of Neurology, have been awarded a National Science Foundation Collaborative Research in Computational Neuroscience (CRCNS) grant. Van de Moortele is serving as a PI and Dr. Henry is serving as a Co-PI, for the research, entitled: "US-France Research Proposal. Hippocampal layers: advanced computational anatomy using very high resolution MRI at 7 Tesla in humans." The grant's duration is 3 years and totals $928,000, with the U.S. portion being $573,342.
Dr. Van de Moortele says that this US-France collaborative research combines two powerful, complementary approaches to explore at a sub-millimeter scale tiny inner structures of the hippocampus, and better understand related functions altered in clinical conditions, with a focus on adult and teenager epileptic patients: 1) cutting-edge imaging methods will be pushed on MRI scanners operating at 7 Tesla to attain unprecedented spatial resolution in multi-contrast modalities, and, 2) high-resolution computational anatomy methods, moving beyond traditional morphometry, will be developed to unveil alterations not detected by conventional means. Dr. Van de Moortele and his colleagues expect that the outcome of this research will pave the way for new biomarkers for diagnosis, prognosis and new therapeutic development.

08/29/16 - David Odde and Colleagues Awarded an $8.2 Million NIH Grant for New Cancer Research Center; IEM Seed Grants Played Early Role
IEM Executive Committee Member Dr. David J. Odde, Professor of Biomedical Engineering, and his team, have been awarded a 5-year, $8.2 Million NIH Physical Sciences in Oncology Center (PSOC) grant from the National Cancer Institute. The development of the center project was supported by two IEM Group Grants since 2013. Dr. Odde is serving as the Project Leader (contact PI) for this Center for Modeling Tumor Cell Migration Mechanics, which is one of a nationwide network of 10 PSOC's. In addition to Dr. Odde, other key leaders include IEM Member Dr. David A. Largaespada (multiple PI), Professor, Department of Cell Biology and Development Genetics, of the Masonic Cancer Center, IEM Member Dr. Paolo Provenzano (core PI), Assistant Professor of Biomedical Engineering, and Dr. Steven Rosenfeld (multiple PI), of the Cleveland Clinic. The center will include a team of biomedical engineers, cancer biologists, surgeons and oncologists from the University of Minnesota, who will collaborate with both the Cleveland Clinic and Mayo Clinic.
While common approaches to fighting cancer involve the attacking of cancer cells, the new center will instead explore how cancer cells can be prevented from migrating and ultimately metastasizing and invading vital organs, which are the primary causes of cancer deaths. The center will perform "integrated modeling and experiments to investigate the molecular mechanics of cell migration and how the tumor microenvironment regulates disease progression as a function of the underlying carcinoma genetics."

08/29/16 - Kamil Ugurbil and Essa Yacoub Among Awardees of $6.9 Million in Grants for Continuation of Human Brain Connectivity Research at CMRR
Dr. Kamil Ugurbil, Professor of Medicine, Neurosciences, and Radiology, and Director of the Center for Magnetic Resonance Research (CMRR), and Dr. Essa Yacoub Professor of Radiology in CMRR, both IEM members, have together received two grants totaling $6.9 million, awarded to the CMRR for the continuation of research to map connectivity of the human brain. The research began nearly 5 years ago as a consortium called the Human Connectome Project (HCP), between the University of Minnesota, Washington University in St Louis, and Oxford University (UK), focused on mapping connectivity in the young, healthy adult brain.
This work is now extended to the study of brain connectivity during aging and development with two new grants involving a larger consortium that includes Harvard and UCLA. "The mapping techniques we created in the HCP are truly transformative, allowing us to better understand how the brain is organized and connected. With these new techniques, we are now in a position to ask about how the brain develops and changes over time, and how it is altered in diseases," says Dr. Ugurbil. IEM Member Dr. Essa Yacoub, Professor of Radiology, will co-lead the development component of the research together with Dr. Kathleen Thomas, Professor, Institute of Child Development, in which changes to the behavior, mood and brains of children in their early years of puberty will be measured against changes to their pubescent hormones. Dr. Ugurbil, together with Dr. Melissa Terpstra, Associate Professor of Radiology-CMRR, will lead the effort focused on studying the effects of aging.

08/29/16 - Kevin Peterson to lead $2.6 Million NIH-Funded Study to Improve Diabetes Care
IEM Member Dr. Kevin A. Peterson, Professor of Family Medicine and Community Health and Director, Center for Excellence in Primary Care, will lead a study supported by a $2.6 million grant from the NIH to determine how primary care providers in Minnesota can improve their care of patients with diabetes. As reported in Medical School Blog and EurekaAlert! , the study will be performed by the University of Minnesota in collaboration with Medica and HealthPartners, and determine which primary care delivery models most likely improve clinical outcomes of Minnesota's diabetic patients, by analyzing data from 2008 to 2019. The timing reflects the state's 2008 establishment of health care delivery criteria, which have since been adopted by a majority of Minnesota's primary care practices. The findings can have a nation impact: "If Minnesota legislation has effectively contributed to improving the clinical outcomes of thousands of people with diabetes, it will provide an important example for the rest of the nation for how to approach improving health care," says Dr. Peterson.

08/29/16 - Kalpna Gupta Discusses with KARE 11 Potential Impact of DEA Decision on the Use of Marijuana for Research
IEM Member Dr. Kalpna Gupta, Professor of Medicine and Co-Chair of the IEM Molecular and Cellular Bioengineering Theme, was interviewed by KARE 11 on a recent Drug Enforcement Agency (DEA) decision that could potentially allow for the use of Cannabis for research from additional sources as compared to only one source through NIDA currently. Dr. Gupta and researchers most often use synthetic cannabinoids, not the actual cannabis-derived medications in their pain research, due to existing DEA regulations. The DEA will continue to maintain the Schedule I status for Cannabis derived products but may consider requests for Medical cannabis from different sources. "I'm hoping that this would be the beginning of a conversation," says Dr. Gupta, to ultimately gain access to Minnesota made medical cannabis products.

08/29/16 - David Jacobs Published in Scientific American with Article on the Positive Impact of Exercise on Cognition
IEM Member Dr. David R. Jacobs, Professor of Epidemiology & Community Health, co-authored an article in Scientific American about how exercise can benefit a person's cognition, both after a workout and in the long-term. While scientists are not entirely certain of how exercise increases brainpower after a workout, one possible reason is that exercise increases the blood flow to the brain and with it, oxygen and other chemicals utilized by the brain. Other possibilities are that exercise creates more mitochondria to generate and sustain brain energy, and that the heart rate increase from exercise increases a person's ability to generate new brain cells. Earlier research performed by Dr. Jacobs showed long-term cognitive benefits of exercise, as 2,747 people between 18 and 30 years of age were followed for 25 years, between 1985 and 2010, with those who were more fit in 1985 performing 10% better in cognitive tests in 2010 than less physically-fit members of their cohort. The conclusion is that regular exercise can benefit a person's cognitive function in the long-term, not just after a workout.

08/29/16 - Colum MacKinnon Conducting Study to Examine Link Between Parkinson's Disease and Sleep Disorder
Dr. Colum MacKinnon, Associate Professor of Neurology, and IEM Member, is researching the link between Parkinson's Disease and muscle activation abnormalities during rapid eye movement (REM) sleep. As reported by Heath Talk , the ultimate objective of Dr. MacKinnon's research is to identify specific aspects of REM sleep that can be predictive of both the onset and progression of Parkinson's Disease, which could lead to earlier diagnosis and treatment of the condition. "The link between REM sleep abnormalities and Parkinson's is probably one of the hottest topics in neurology," says Dr. MacKinnon. Up to 60% of people suffering from Parkinson's experience significant sleep issues, in particular, muscles that should be "turned-off" during REM sleep are instead turned-on. These symptoms are often seen many years before a diagnosis of Parkinson's disease is made and are likely indicative of a "pre-Parkinsonian state." Dr. MacKinnon notes that the University of Minnesota has the "longest history of any institution of following this particular sleep problem," and was the first to make this link. He adds that the Center for Magnetic Resonance Research (CMRR) provides "state-of-art imaging of the brain" that will allow them to assess the changes in brain structure and function that occur as the disease progresses.

08/29/16 - Visible Heart Lab Featured on Big Ten Network and in Medtech Pulse
The Big Ten Network and Medtech Pulse recently featured the IEM-affiliated Visible Heart Lab and video of its various functions, including the reanimation of hearts from both pigs and humans. While the pig heart reanimations occur regularly for educational and research purposes, human heart reanimations occur very infrequently. "On the rare occasion [when] the heart is deemed not viable [for transplant], we get it to the lab within four to six hours," says Dr. Paul A. Iaizzo, Professor of Surgery, Principal Investigator of the Visible Heart Lab and IEM Associate Director for Education and Outreach. Videos and images of the reanimated hearts are placed on the Atlas of Human Cardiac Anatomy, a free website, that had 500,000 users, globally, in 2015. The Visible Heart Lab was started in collaboration with Medtronic, which has also been its primary sponsor.

08/29/16 - Michael Garwood is Member of Team that Developed MRI Technique to Detect Cracks in Teeth
IEM Member Dr. Michael Garwood, Professor of Radiology-CMRR, is among a team of researchers who have developed an MRI-based technique for detecting cracks in teeth called SWeep Imaging with Fourier Transformation (SWIFT). According to Dr. Garwood, "SWIFT is a unique imaging technique because it allows the MRI machine to capture fast-decaying signal from tissue, which is why regular MRI is not able to image bone and teeth." As reported in Health Talk , SWIFT can detect cracks only 20 micrometers wide, approximately the size of two red blood cells. While MRI machines tend to be too costly for dental offices, the technique, and resulting understanding of cracks in teeth, can help to improve current dental care and can also be used to identify ways in which imaging can be improved for dental applications.

07/27/16 - AIMBE Executive Director Milan Yager to Speak at IEM Seminar on September 13, 2016
The Institute for Engineering in Medicine (IEM) will host a seminar, "The Science Behind Failed Public Policy," by Dr. Milan P. Yager, Executive Director, American Institute for Medical and Biological Engineering (AIMBE) on Tuesday, September 13, 2016 from 12:00pm-1:00pm.
The abstract for Dr. Yager's seminar is as follows: "Today, federal funding for biomedical research, as a percentage of federal spending, has fallen to the lowest level in modern history. For far too many years NIH has been receiving increasing numbers of grant applications and funded fewer and few. What life-saving idea was among the 41,000 grant applications that were not funded last year? The most powerful country in the world, with the strongest economy and the greatest wealth, has made the spending decisions causing Federal research, and specifically, biomedical research, to be nearly flat for over a decade. If the American public recognizes and supports more funding for biomedical research why hasn't Congress responded? If biomedical research has such a high ROI and significant financial return, why isn't America investing more? The reasons behind the failed public policy not to invest in biomedical innovation is actually quite simple. It begins with a story. This discussion of policy and politics might not be what you are expecting. But it surely will impact your research, life, and wellbeing."
07/27/16 - IEM Seed Funding Leads to $3 Million R01 for Brenda Ogle
An IEM Exploratory Grant in 2014 has led to a $3 Million R01 grant for which IEM Member Dr. Brenda A. Ogle, Associate Professor of Biomedical Engineering, is a Principal Investigator. The IEM grant "provided funds to support preliminary experiments that led to the R01 submission," says Dr. Ogle, who is collaborating with former IEM Executive Committee Member Dr. Jianyi Zhang, now Chair of the Department of Biomedical Engineering at the University of Alabama-Birmingham. The R01 grant "Stem Cell Therapy for Myocardial Repair" will explore the use of 3D printing of replacement grafts to repair the heart tissue of patients who have experienced myocardial infarction. Dr. Ogle says that "if successful, 3D printing of cardiac tissues will improve outcomes of acute cardiac injury and will inform prospects for generating intact organs."
07/27/16 - Visible Heart Lab is Stimulating Environment for Students
The IEM-Affiliated Visible Heart Laboratory has evolved into becoming a great place for students to learn about cardiac anatomy and harness the capabilities of 3D printing. As reported by the Minnesota Daily, the lab, which was established in 1997, has been at the forefront of heart research, including the reanimation of human hearts. Approximately 45 students work in the lab, and their enthusiasm for the research creates a very positive work environment. "It's the fun part about the job; it's really working with the young mind and talent; they keep things moving forward," says the Visible Heart Lab's Principal Investigator, Dr. Paul A. Iaizzo, Professor of Surgery and IEM Associate Director for Education and Outreach. More recently, the lab has become one of the 3-D printing hubs for clinical applications at the University of Minnesota. "We scan human hearts with CT and/ MRI and then we can create the digital models," says Dr. Iaizzo. "Once you've created the digital models, you might as well try and print 'em."

07/27/16 - Alan Hirsch Discusses with KARE 11 Campaign for Use of Aspirin to Prevent Heart Attack and Stroke
IEM Member Dr. Alan T. Hirsch, Professor of Medicine, Epidemiology and Community Health, Director of the Vascular Medicine Program and Co-Director of the Minnesota Heart Health Program, discussed with KARE 11, the "Ask about Aspirin" campaign for the prevention of heart attack and stroke. Dr. Hirsch says that, for individuals between the ages of 50 and 69, taking a daily low-dose aspirin can lower the risk of heart attack or stroke by 20%, resulting in as many as 11,000 to 12,000 fewer of these incidents over the lifetime of those who might benefit from the campaign in Minnesota. Dr. Hirsch, noting that aspirin use has both benefit and risk, advises that all individuals know their individual benefit and risk, and first discuss this approach with their primary care physician. "Aspirin is usually safe and effective," says Dr. Hirsch, "but has to be right for the individual. What should you do?: 'Ask about aspirin!'".

07/27/16 - Gwenyth Fischer Discusses Life-Saving Pulse Oximeter Neonatal Screening with Pioneer Press
IEM Member Dr. Gwenyth Fischer, Assistant Professor of Pediatrics, discussed with the Pioneer Press the use of pulse oximeters on newborns to detect potentially life-threatening congenital heart defects so that they can be treated. While the technology has been used in pediatrics for decades, it has more recently become commonplace in the U.S. as a screening tool for congenital heart disease, largely due to the efforts of Minnesotan Annamarie Saarinen, who lobbied the federal government to make pulse oximeter neonatal screening mandatory. Dr. Fischer says that the technology has made a significant impact, as she "can personally attest to several babies caught here with congenital heart disease before they left, potentially saving them from disaster." Ms. Saarinen has since worked with a California-based company to develop a portable and affordable mobile version of the technology to make it viable for screening newborns in developing nations, where its use is being supported by the Newborn Foundation, a St. Paul-based nonprofit founded by Ms. Saarinen.

07/27/16 - Research Team Led by Louis Mansky Makes Significant Discovery about Uniqueness of Retrovirus Structures
A team led by IEM Member Dr. Louis M. Mansky, Professor of Diagnostic & Biological Sciences and Microbiology & Immunology and Director of the Institute for Molecular Virology, has discovered that the structures of retroviruses tend to be distinctive from one another, which has significant implications for future retrovirus research. As reported in Science Daily, Dr. Mansky says "most researchers assume that all retroviruses are just like HIV, but they're not. We cannot take a one-size-fits-all approach when studying retroviruses and discovering new strategies for antiviral treatments or vaccines." Dr. Mansky hopes that the findings will serve as a foundation from which scientists can "determine how to stop these viruses from causing deadly diseases in humans such as cancer and AIDS."

07/27/16 - SpaceX-9 Mission Includes Bruce Hammer's Experiment to Evaluate Accuracy of CMRR Microgravity Simulator
On July 17th, the SpaceX-9 mission successfully launched a rocket toward the International Space Station containing a research experiment from IEM Member Dr. Bruce E. Hammer, Professor of Radiology at the Center for Magnetic Resonance Research (CMRR). As reported in Space Online , the experiment will test the accuracy of a device at the CMRR that simulates microgravity for researching bone loss in space, by evaluating changes in bone cells in the microgravity environment of the low-Earth-orbiting space station. The results will then be matched with those of the same experiments performed at the CMRR, to determine if the simulator's microgravity environment is sufficient for this research. If so, it will provide a ground-based platform to study how simulated microgravity affects cell function. Doing experiments aboard the ISS is difficult due to crew time availability, limited access, cost and logistics required to bring a payload to and from low earth orbit. "When you're doing experiments on Earth that simulate microgravity, you're in a much better-controlled environment," says Dr. Hammer.
06/27/16 - IEM Director Named Recipient of the Prestigious IEEE Biomedical Engineering Award

06/27/16 - Stephen Haines Featured on KSTP for Treatment of Young Patient with Brain Condition
IEM Member Dr. Stephen J. Haines, Professor and Department Head of Neurosurgery, was featured in a KSTP story for his treatment of a patient with Hydrocephalus, referred to as "water on the brain," an incurable condition that affects more than one million Americans. "If for some reason you make more spinal fluid than you absorb back into your blood stream, the fluid will build up and cause increased pressure in the head," says Dr. Haines. His patient, an eight-year-old boy, developed the potentially life-threatening condition following a premature birth. Dr. Haines can treat Hydrocephalus by either popping the membrane that holds the fluid or by installing shunts, and for this patient, he installed two shunts that will connect together and drain the fluid to the child's belly. The patient and his family established a foundation and organized a golf tournament to support Hydrocephalus research and increase awareness of the condition.

06/27/16 - Walter Low & Dan Garry Discuss with BBC & CNN Use of Chimeras for Transplant
IEM Members Dr. Walter C. Low, Professor of Neurosurgery, and Dr. Daniel Garry, Professor of Medicine and Director of the Lillehei Heart Institute, discussed with the BBC and CNN research on the growing of human organs in pigs to be used for transplant, and the issues associated with it. Dr. Low says that the technique could potentially be used to create a number of different types of organs and cells, including pancreas, heart, liver, kidney, lung, cornea, and immune cells; and that "the organs and cells would be exact genetic copies, but much younger and healthier versions, and you would not need to take immunosuppressive drugs which carry side-effects." Dr. Garry states that these personalized humanized organs in gene-edited animals would provide new pre-clinical research models that would be invaluable to study the impact of emerging therapies and disease progression.
However, the NIH has banned funding this research due to concerns of the resulting chimeras developing human cognitive states. Dr. Garry objects to the ban due to its inhibition of medical progress and the creation of a stigma associated with the research. And Dr. Low says that this risk can be avoided. "We can address this issue by examining the brains from each type of chimera that is generated to produce a specific type of organ. For example, if in generating liver chimeras we observe that the pre-term brains also exhibit substantial off-target contribution to areas such as frontal cortex then these fetuses would not be allowed to be born."

Dr. Jakub Tolar, Professor of Pediatrics, Director of the Stem Cell Institute and IEM Member, will treat a child from Canada who suffers from Epidermolysis Bullosa (EB), a rare and potentially-fatal skin disease. As reported by the Ottawa Sun, the child, who's nicknamed "Butterfly Boy," will travel to the University of Minnesota to have a blood and bone marrow transplant as part of a clinical trial being led by Dr. Tolar. "The advantage of bone marrow transplant is that you don't just treat a single patch of skin: This is a whole body approach," says Dr. Tolar. While he warns that the treatment doesn't work for all patients, it can have a very positive impact when it does work. "You can go from a kid who is in constant pain, who is wheelchair bound, who has bandages changed for several hours, to someone who goes to school, to the beach, plays in the orchestra, and goes on with his life," says Dr. Tolar.

The 4th Minnesota Neuromodulation Symposium attracted 483 registrants to its two-day event, which was organized by IEM and held at the Commons Hotel on April 14th and 15th. The globally-recognized event featured plenary, invited and highlight talks, and panel discussions by the leaders of the neuromodulation field, from academia, government, and industry. In addition, there were close to 100 poster presentations representing 37 different institutions, 18 non-profit organizations, 10 corporations and 12 countries.
The groundbreaking research of two of the Symposium presenters has made national news in April. Plenary speaker Dr. Alvaro Pascual-Leone of Harvard University was featured on NPR's Fresh Air on April 21st for his work in utilizing transcranial magnetic stimulation (TMS) for treating patients with autism. Among the highlight talks and posters presented was "Implanted Brain Computer Interface for Real-Time Cortical Control of Hand Movements in a Human with Quadriplegia," research that was featured in the New York Times during the same week and published in the April 13th online edition of the journal Nature.
"The quality of presentations at the symposium represents one of the finest conferences in the world. The success of the symposium reflects the emerging nature of the neuromodulation field and the leading positions of the University of Minnesota and Minnesota neuromodulation industry," said Dr. Bin He, Symposium Chair and Director of the Institute for Engineering in Medicine.

04/29/16 - 3-D Modeling Plays a Vital Role in TAVR Success; Shows Promise for Wide Range of Medical Procedures
The Laboratory of Dr. Paul A. Iaizzo, Professor of Surgery and IEM Associate Director for Education and Outreach, collaborated with cardiologist Dr. Gregory A. Helmer to generate a 3-D model of a patient's heart to find the optimal size for replacement of her aortic valve. Having the right sized valve was particularly critical to the success of this transcatheter aortic valve replacement (TAVR) procedure performed at the University of Minnesota Medical Center. Such modeling performed by Dr. Iaizzo's team at the IEM-affiliated Visible Heart Lab continues to show the promise for such technologies to improve patient outcomes in a variety of procedures. "We hope that for clinical teams to have such a resource like this at the University will be something that will ultimately improve care delivery," says Dr. Iaizzo.

04/29/16 - Mind-Controlled Drone Race Utilizes Technology First Demonstrated by IEM Director
The University of Florida hosted last weekend what was billed as the first-ever race between mind-controlled drones, utilizing a technology that was first demonstrated at the University of Minnesota in 2013 by Dr. Bin He, Director of IEM and Center for Neuroengineering and Professor of Biomedical Engineering. As reported by the Associated Press, The race, which was held in an indoor basketball court, involved 16 "pilots" who strove to fly a drone through a 10-yard course. Dr. He's group demonstrated in 2013 mind-controlled drone flying in a gym on the campus of the University of Minnesota, which stimulated a number of world-wide efforts on non-medical application of brain-computer interface (BCI). Organizers of the race are seeking to make BCI more mainstream, by having it used for everyday tasks, beyond laboratory settings and medical applications, a future that is becoming more viable as BCI equipment becomes more affordable. "The progress of the BCI field has been faster than I had thought ten years ago. We are getting closer and closer to broad application," says Dr. He.

04/29/16 - Douglas Yee Working to Efficiently Evaluate Breast Cancer Drugs
IEM Member Dr. Douglas Yee, Professor of Medicine and Director of the Masonic Cancer Center, serves on the Executive Committee and is Co-Chair of the Agent Committee of the I-SPY2 clinical trial, which has successfully evaluated several breast cancer drugs simultaneously, with three of those now progressing to the next phase of testing. This approach is unique from that of most clinical trials, in which drugs are tested one at a time, and it saves a lot of time in a process that typically lasts for five or more years for each drug. "To me, it demonstrates that we can identify active agents that are effective in the treatment of breast cancer in a much shorter timeline," says Dr. Yee. The multi-center trial has tested 15 chemotherapy drugs since it began in 2010, and focuses on both the effectiveness of the various drugs as part of a chemotherapy regimen prior to surgery and matched to the molecular profile of a patient's tumor so that the most effective of the drugs can be used for each patient. An arm of the trial is being developed to switch the drug for patients who don't respond sufficiently to their initially matched treatment.
04/29/16 - Roni Evans Discusses Challenge of Studying Chronic Pain's Impact on Young Adults in Story Picked Up by Associated Press
IEM Member Dr. Roni L. Evans, Associate Professor, Center for Spirituality and Healing, recently discussed the challenges of researching chronic pain in young adults with the Minnesota Daily, a story that was reported by the Associated Press and also ran in the Star Tribune and MPR. Chronic pain is reported by approximately one-quarter of people 18 to 29 years of age, and can significantly affect their lives by limiting them from activities they enjoy and isolating them socially. But studying pain in young adults can be challenging due to the subjective nature of measuring it. Dr. Evans says that "You can't see that someone has pain. It's not like a broken leg or a broken arm; it is something that someone experiences, so you really have to rely on what they're telling you...and that makes it hard to study."

04/29/16 - Jeffrey McCullough Discusses Zika Virus in New York Times
Dr. J. Jeffrey McCullough, Professor of Laboratory Medicine and Pathology, American Red Cross Professor of Transfusion Medicine, and IEM Member discussed with the New York Times the logistical challenges of keeping the Zika virus from contaminating blood supplies in effected areas. The FDA approved a new test to screen donated blood, which is needed to avoid the contamination of blood supplies as the virus spreads into the U.S. Without such screening, blood banks in areas most likely to be hit with outbreaks, such as the Gulf Coast states, would have had to import supplies from northern states not yet effected by the virus. "It is logistically difficult, but it can be done," said Dr. McCullough. But the new screening test, which will be initially implemented in Puerto Rico, will help to newly-effected areas to avoid that situation.

03/29/16 - Kelvin Lim Discusses Traumatic Brain Injury's Psychological Impacts and Treatment Strategies
IEM Executive Committee Member Dr. Kelvin O. Lim, Professor and Vice Chair for Research of the Department of Psychiatry, discusses in MinnPost the long-term psychological impact of traumatic brain injury (TBI) and new treatment strategies to address it. TBI, which is often the result of car accidents or combat, can lead to behavioral changes and depression as connections between neurons are damaged, disrupted or disconnected. One of the treatment strategies being explored by Dr. Lim is the mapping of brain-circuit abnormalities and determining whether those can be addressed with transcranial magnetic stimulation (TMS), which will be investigated in a new study conducted at the VA. The effectiveness of TMS and other stimulation techniques to treat TBI is "of great interest to us here at the university," says Dr. Lim.
Psychological Impact of Brain Injury can be Long-Lasting
03/29/16 - FDA Releases New Guidance for Neurological Devices
On March 4th, the FDA released draft guidance on considerations for "Medical devices intended to slow, stop, or reverse the effects of neurological disease face challenges with regard to collecting safety and efficacy data in a clinical study, when less invasive pharmacotherapy approaches may be better understood or more-well accepted in the clinical community." As reported by the Regulatory Affairs Professionals Society, the guidance can apply to devices that treat the progression of neurological diseases, such as Parkinson's, Alzheimer's and primary dystonia. The agency's statement says that "study designs should aim to distinguish between symptomatic benefit(s) and disease-altering benefit(s) that slow disease progression and quantify the magnitude of such benefits in terms of biomarkers and clinical outcome assessments."

03/29/16 - Richard James Proposes Using Twisted X-Rays for Structure Determination
IEM Member Dr. Richard D. James, Professor of Aerospace Engineering and Mechanics, and his colleagues have discovered that twisted X-rays could be used as a better method of performing X-ray crystallography in materials science and biology research. As reported by the International Union of Crystallography, twisted X-rays could better define yet-unknown helical structures than traditional approaches as many of these structures "do not readily crystallize as three-dimensional periodic structures," and the process of crystallization can alter materials. The twisted X-rays could overcome these limitations by "matching the symmetry of the incoming radiation to the symmetry of the structure to be studied." Dr. James says that he and his students are now investigating how to build a source for twisted X-rays, which is challenging because the ability to manipulate X-rays is limited.

03/29/16 - Andrew Grande Treats Painful Nerve Condition with Surgery
IEM Member Dr. Andrew W. Grande, Assistant Professor, Neurosurgery and Co-director of the University of Minnesota's Earl Grande Stroke and Stem Cell Laboratory, performs a surgical procedure to address Trigeminal Neuralgia (TN), a very painful nerve condition. While most of the approximately 150,000 patients diagnosed with TN each year in the U.S. can be treated with medication, some require brain surgery to relieve the pain. One such patient is a mother of four from Hudson, Wisconsin, who's experience with the condition and successful surgery by Dr. Grande are profiled in the Hudson Star- Observer. The surgical procedure, called microvascular decompression, relieves pressure on the trigeminal nerve.

03/29/16 - Emil Lou Discusses Aspirin's Ability to Reduce Cancer Risk
Dr. Emil Lou, Assistant Professor of Medicine and IEM Member, discussed the findings of a recent study published in JAMA Oncology showing that regular use of aspirin can lower a person's cancer risk. As reported by the Academic Health Center's publication Health Talk, the research was based on data from large, decades-long studies of 88,000 women and 47,000 men. The impact was most significant for gastrointestinal cancers, including a 19% reduction for colorectal cancer. Aspirin use to achieve this reduction resulted from taking from .5 to 1.5 tablets per week for a minimum of 6 years. Dr. Lou says that the study "represents one of the most comprehensive studies to date supporting regular aspirin use as a low-cost intervention to help decrease the risk of gastrointestinal cancers."
Benefits of Aspirin May Include Lower Cancer Risk
03/29/16 - IEM Members Offering Cell-Based Therapy Training to University of Minnesota Physicians and Scientists
IEM Executive Committee Member Dr. Allison Hubel, Professor of Mechanical Engineering, and IEM Member David H. McKenna, Jr., Associate Professor of Lab Medicine and Pathology, are directing the Hematology Workforce Training Program, which seeks to directly address the growing need for researchers with cell-based therapy skills. "The ability to treat all of the millions of patients who would benefit from these therapies is limited in part by the lack of trained physicians and scientists in this field," says Dr. Hubel. Funded by an NIH Research Education Program (R25) grant, this short-term training program is customized to a trainee's specific needs and interests and involves both one-month rotations and a research project that are customized to the trainee's career needs. The program is actively recruiting new trainees.

02/29/16 - Paul Iaizzo Discusses 3-D Printing in Washington Post
Dr. Paul A. Iaizzo, Professor of Surgery and IEM Associate Director for Education and Outreach, discusses the application of 3-D printing of hearts to surgery, medical device design and education in a recent edition of the Washington Post. The surgical applications include the printing of a model heart prior to surgery to help the patient and family members better understand the situation and provide them with the peace-of-mind that comes from understanding it. "It's powerful and comforting for parents to really understand what the problem is," says Dr. Iaizzo. The educational applications include the use of printed hearts for surgical residents and students in the medical school, which Dr. Iaizzo says "puts that anatomy in the brain in a three-dimensional way that never could have been done another way."

02/29/16 - John Bischof Discusses Organ Preservation in Economist
John C. Bischof, Professor of Mechanical Engineering and IEM Associate Director for Development, has a proposed solution to one of the major challenges of warming cryopreserved organs: heating the tissue quickly and uniformly enough to avoid the damage that would occur from the crystallization or cracking (fracture) that would otherwise occur during the process. Dr. Bischof's approach is to apply tiny (nano) particles of magnetite to the cryoprotectant fluid that bathes the organ, then heat them and the organ by placing the system in a fluctuating magnetic field, an approach he has successfully tested on heart valves and arteries. It is one of several approaches presented in a recent Economist article to allow for the better cooling and warming of organs to achieve the ultimate objective of making many more of them available for transplantation.

02/29/16 - Louis Mansky's Research Could Lead to More Affordable HIV Drugs
IEM Member Dr. Louis M. Mansky, Chair of the Department of Diagnostic and Biological Sciences and Director of the Institute for Molecular Virology, was the lead author of a recent study showing how an RNA-based nucleoside, 5-aza-C, blocked the ability of HIV to spread. As reported in Infection Control Today, this could lead to more affordable HIV medications because RNA-based drugs can be produced in large quantities at a lower cost than most currently available HIV drugs, which are DNA-based. Dr. Mansky says that while 5-aza-C is not as effective at treating HIV as those current drugs,"we can use what we know to try mimicking 5-aza-C to discover new compounds that could be more effective while still being more affordable to produce." The study is being published in the American Society for Microbiology's journal Antimicrobial Agents and Chemotherapy.

02/29/16 - Research by John Osborn Shows that Drug-Resistant High Blood Pressure can be Controlled by Renal Denervation
Dr. John Osborn, Professor of Integrative Biology & Physiology, and IEM Member, was the lead investigator of a study showing that drug-resistant hypertension can be treated by completely ablating nerves to the kidneys. As reported by Medical Xpress, the research shows that arterial blood pressure was lowered when both efferent and afferent nerves between the brain and kidneys were ablated, but not when ablating only the afferent nerves. As a result, Dr. Osborn says that, "Although catheter-based renal nerve ablation is now possible, catheter design needs to be improved since present catheters appear only to partially denervate the kidney. Clearly, it is also important to develop a method to assess the completeness of denervation at the time of the procedure." The research was published in the American Journal of Physiology-Regulatory, Integrative, and Comparative Physiology.

02/29/16 - David Jacobs Conducts Research Showing that Environmental Contaminants in Low Doses Can Harm the Brain
IEM Member Dr. David R. Jacobs, Professor of Epidemiology & Community Health, was among a group of investigators who conducted research showing that persons who are repeatedly exposed to organochlorine pesticides (OCPs), such as DDT, are at greater risk for cognitive impairment. As reported by EurekAlert!, the research included approximately 1,000 individuals at 70 years of age in Uppsala, Sweden. Those with high levels of OCPs in their serum were found to have had three times the risk of future cognitive impairment compared to others who had low levels of the containments. While OCPs were already known to be neurotoxins, the findings are surprising because it shows that even a low level of exposure to OCPs can be harmful if it occurs during a long period of time. The research was published in Environmental International.

02/29/16 - Walter Low and Ann Parr Discuss Relevance of Fetal Tissue to their Research in Treating Parkinson's and Spinal Cord Injury
IEM Members Drs. Walter Low and Ann Parr discuss the importance of fetal tissue to their research in a recent Star Tribune article highlighting the work of several University of Minnesota researchers who are using these types of cells. Walter C. Low, Professor of Neurosurgery, uses them as a positive control against which to assess the effective phenotype of differentiated stem cells from sources other than fetal tissue. "Our goal is to one day take a piece of your skin and make that into a pluripotent stem cell ... that makes dopamine neurons for treating Parkinson's patients," says Dr. Low. A more direct use of fetal tissue stem cells is being explored by Dr. Ann M. Parr, Assistant Professor of Neurosurgery and Director of Spinal Neurosurgery, who is determining whether they can be used to repair damage to the spinal cord. "There are lots and lots of people out there who have chronic spinal cord injury and there is nothing to offer them" says Dr. Parr, who adds "it's the first time this has been a possibility."

01/29/16 - Bob Tranquillo's Pediatric Heart Valve Research Featured on KARE11
The pediatric heart valve development by IEM Member Dr. Robert T. Tranquillo, Professor and Head of the Department of Biomedical Engineering, was recently featured on KARE 11. Dr. Tranquillo is using decellularized tissue tubes grown in the lab from adult skin cells to develop a pediatric heart valve that will grow as the child does, eliminating the need for multiple surgeries, as children outgrow currently-available heart valves. "Our goal is to create an option that requires only one surgery," says Dr. Tranquillo, who has tested the valve in animals and plans to soon approach the FDA about progressing to a human clinical trial for a replacement of the artery in which the valve resides.

01/29/16 - Pediatric Device Innovation Consortium Profiled by Star Tribune
The Pediatric Device Innovation Consortium (PDIC), founded by IEM Member Dr. Gwenyth Fischer, Assistant Professor of Pediatrics, was profiled in the Star Tribune. The PDIC helps to shepherd the development of pediatric devices from their inception to their adoption by industry through grants and guidance to clear the regulatory, reimbursement and other hurdles that typically keep these devices from reaching the patients who need them. "What we'd like to do is take products as far as possible with university help, so that when they exit the university system into industry, they are much more likely to succeed," says Dr. Fischer. The University of Minnesota's Office of Discovery and Translation is providing approximately $250,000 in 2016 to support the PDIC's programs, including planned access to a pediatric device incubator and a program to solicit ideas from parents, in addition to engineers and physicians. The incubation will be done through collaboration with DesignWise Medical, founded by Bradley Slaker, current Innovation Fellow of the IEM-Affiliated Medical Devices Center.

01/29/16 - Enhanced Neuron Imaging Technique Developed by Karen Mesce
IEM Member Dr. Karen A. Mesce, Professor of Neuroscience and Entomology, has developed a novel technique for the imaging of silver or gold-labeled tissue samples in a collaborative effort with colleagues at Agnes Scott College. As reported in the journal eLIFE, the new technique combines spectral confocal microscopy with the metal-staining of neurons. This results in neuronal tissue and cell specimens that are easily imaged in 3D and will allow for the re-imaging of older metal-impregnated samples that have been archived, even as imaging techniques continue to improve in the future. "The progression or stability of cancer or other disease could therefore be charted with accuracy over long periods of time," says Dr. Mesce.

01/29/16 - Valerie Pierre Developing Urinary Tract Infection Diagnostic Tool
IEM Member Dr. Valerie C. Pierre, Associate Professor of Chemistry, is developing a new tool for fast, affordable diagnoses of urinary tract infections (UTIs), which affect nearly half of all women during their lives. Urine cultures have been the most accurate method to diagnose UTI's, but because they typically take 48 to 72 hours, and more urgent treatment is needed, the diagnoses are often based upon symptoms, which are not as reliable. Dr. Pierre's method aims to make a more accurate rapid diagnosis and assess the bacteria's antibiotic resistance to determine the best course of treatment. CTSI provided critical support to Dr. Pierre, including funding, guidance and the facilitation of her collaboration with the Mayo Clinic. A prototype of the tool is being tested on clinical samples and long-term plans include submitting it to the FDA for approval.

12/22/15 - IEM Members Working to Improve Recovery from Stroke
IEM Members Drs. Bin He, James Carey, and Andrew Grande were profiled by the University of Minnesota Foundation for their work in developing treatments that could help stroke patients to regain some of their functionality. Dr. Bin He, IEM Director and Professor of Biomedical Engineering, is exploring how the application of his Brain-Computer Interface (BCI) technology can restore this functionality by stimulating and reactivating the brain tissue that has been injured. Dr. James R. Carey, Professor of Physical Medicine and Rehabilitation, is exploring the approach of strengthening areas of the brain affected by stroke by temporarily inhibiting unaffected areas. Dr. Andrew W. Grande, Assistant Professor, Neurosurgery and Co-director of the University of Minnesota's Earl Grande Stroke and Stem Cell Laboratory, is exploring how genetically-reprogramming glial cells can transform them into mature neurons. These approaches can have a tremendous impact as approximately 800,000 Americans experience a stroke annually, and there are approximately 6.5 million stroke survivors in the U.S.

12/22/15 - Stephen Haines & Samuel Levine Researching the Long-Term Results of Acoustic Neuroma-Removal Technique
IEM Members Drs. Stephen J. Haines and Samuel C. Levine are determining whether a technique of removing acoustic neuromas that seeks to preserve hearing and facial control, will work in the long-term. As reported by the University of Minnesota Foundation, the procedure significantly improved outcomes from what had been the standard procedure. Through this technique, "About 70 percent of our patients retained their hearing," says Dr. Stephen J. Haines, Professor and Department Head, Department of Neurosurgery and Lyle A. French Chair.
Drs. Haines and Levine started publishing their findings in 1993. Due to the longevity of their collaboration,the technique has now been performed for a long enough period of time to measure its effectiveness. "The thing that's powerful is when you get 25 to 30 years' worth of data," says Dr. Samuel C. Levine, a Professor in the departments of Neurosugery and Otolaryngology, who started the database from which the results are being studied. "If it turned out that we preserved hearing right after surgery, but it was all gone in five years, that wouldn't be a strong reason to have the operation," says Haines. "But if it's going to last the rest of their lives, it would make a huge difference in indication for the surgery. It made a big difference for Sally."

Dr. David R. Jacobs, Professor of Epidemiology & Community Health, and IEM Member, was the co-author of a study published recently in "JAMA Psychiatry" that links television-watching and low levels of physical activity with lower cognitive function in midlife. The study followed more than 3,000 adults for 25 years, from early adulthood to midlife, addressing both their television viewing habits and levels of exercise at least three times per year.
The study was also featured in "Ars Technica", which highlighted that the study is among the first to include the impact of television-watching and cardiorespiratory fitness on midlife cognitive function. According to that article, "these risk behaviors may be critical targets for prevention of cognitive aging even before middle age."

12/22/15 - Hubert Lim Discusses the Effectiveness of Sound Therapy
Dr. Hubert H. Lim, Assistant Professor of Biomedical Engineering, Institute for Translational Neuroscience Scholar, and IEM Member, was interviewed by Minnesota CBS affiliate WCCO about the practice of sound therapy, which can be used to treat conditions commonly addressed by more traditional treatments, such as chiropractic intervention or massage therapy. Dr. Lim's lab is exploring if and how these types of physiological and neural effects can be systematically controlled to relieve certain disease symptoms or enhance other conventional treatments, leading to new directions in integrative medicine.
According to Dr. Lim, "it is clearly doing something in the body, in the brain. When you measure signals in the body you will see the heart rate will change, people will sweat or have chills for different types of sounds, so it is clearly causing a physiological neural effect."

11/24/15 - IEM Launches Clinical Immersion Program
The Institute for Engineering in Medicine is pleased to announce the successful launch of its new Clinical Immersion Program, in which groups of engineers from medical technology companies visited the University of Minnesota in September and October. During the week-long program, the participants observed numerous surgical procedures and learned about the many challenges and unmet clinical needs associated with treating patients with heart disease, cancer, and other very serious conditions.
Hosted by the Department of Surgery, the program seeks to help engineers become more effective in developing leading-edge medical technologies. Among the participants was Dr. Aditee Kurane, an R&D manager at St. Jude Medical. "We got to see so many aspects of the clinical setting that we had no previous exposure to - grand rounds, listening to detailed case preparation by the surgical residents and most importantly, a variety of surgical procedures where the surgeons were so accommodating and explained details of the procedures to help us truly understand what was going on," said Dr. Kurane. IEM is currently organizing company groups for Spring 2016.

11/24/15 - Timothy Church and Douglas Yee Discuss New Breast Cancer Screening Guidelines
The American Cancer Society's new guidelines for breast cancer screening encourage women to make the decision on when, and how often, to go in for testing. Under the new guidelines, women of average risk are recommend to be screened annually starting at age 45, and then every other year starting at age 55. As reported in a story by the "Minnesota Daily," having annual exams at earlier ages could lead to false-positives. The co-author of the study that led to the new guidelines, Dr. Timothy R. Church, Professor of Environmental Health Sciences, and IEM Member, says "When you screen for any disease, the tests are not perfect, so sometimes they'll indicate a disease is present when it isn't."
In another article on the topic in the University of Minnesota's "Health Talk," IEM Member Dr. Douglas Yee, Professor of Medicine and Pharmacology, Director of the Masonic Cancer Center and John H. Kersey Chair in Cancer Research, says "The new ACS guidelines are based on a systematic evidence review of breast cancer screening literature including randomized controlled trials, more recent observational studies, and simulations." Dr. Yee notes, however, that the new guidelines are not appropriate for women at high-risk of breast cancer, such as those possessing the inherited BRCA mutation.

11/24/15 - Esther Krook-Magnuson Explores Optogenetics in Epilepsy
Dr. Esther Krook-Magnuson, Assistant Professor of Neuroscience, MnDRIVE Neuromodulation Scholar, and IEM Member, is researching how brain activity during epileptic seizures can be altered using light, a technique known as optogenetics. As reported in the University of Minnesota's Health Talk Publication, medication is unable to control seizures in as many as 40% of epilepsy patients, resulting in a need for other approaches. Optogenetics can potentially address this by targeting the specific groups of cells that cause the seizures and adjusting the activity within the cells. Dr. Krook-Magnuson says that "Optogenetics is the tool we've been waiting for." Her research is supported by both MnDRIVE and the NIH.

10/30/15 - Michael McAlpine Applies 3-D Printing to Nerve Regeneration
Dr. Michael McAlpine, Benjamin Mayhugh Associate Professor of Mechanical Engineering and IEM Member, is working on ways to regenerate complex nerve injuries with 3-D printed scaffolding to serve as a conduit between the ends of a broken nerve network, as reported in M.I.T.'s "Technology Review." The impact of this type of nerve regeneration is potentially significant as more than 200,000 procedures to repair nerves are performed annually in the U.S., and the approach can eliminate some of the issues associated with the current practice of harvesting and using nerve tissue from other parts of the body. Dr. McAlpine recently came to the University of Minnesota from Princeton University and presented aspects of this research during an IEM Seminar in September. He says that, as he continues his research, he would like to identify a biodegradable material that could be used for the scaffolding so that it can dissolve in the body after the nerve has been regenerated. This advance will set the stage for future clinical trials in humans.
3-D Printing's Next Act Nerve Regeneration
10/30/15 - Visible Heart Lab Serving as Research Site for Lung Perfusion System Aimed at Increasing Lung Transplant Availability
The University of Minnesota's Visible Heart Lab (VHL), directed by Dr. Paul A. Iaizzo, Professor of Surgery and IEM Associate Director for Education and Outreach, is the sole research site for the testing of the TransMedics OSCTM Portable Lung Perfusion System, which will help to make more lungs available for transplantation. "With only 20% of all lung offers currently used for transplant and a growing need for quality donors, our research with Ex vivo lung preservation (EVLP) is a critical step toward addressing this shortage," says Dr. Gabriel Loor, M.D., Assistant Professor of Surgery, who is performing this research with Dr. Iaizzo.
The OSC system preserves lungs by continuously pumping blood through them as they are being transported from the donor to the recipient. This practice increases the time available between harvest and transplant as compared to the current practice of placing the harvested lungs on ice. This added time would increase the number of lungs available for transplants. The Visible Heart Lab is uniquely capable of performing the studies needed to evaluate the OSC system's various aspects, and the resulting research is described in two journal articles that are currently under review, one in the "Journal of Thoracic and Cardiac Surgery" and the other in the "Journal of Heart and Lung Transplantation." TransMedics expects its OSC system to soon enter clinical trials in the U.S., although it is already available for commercial use in Europe and Australia.

10/30/15 - New Cancer Immunotherapy Company Established to Commercialize Technology Developed by Carston Wagner
Tychon Biosciences, a new biotechnology company, has started to commercialize an adaptive immunotherapy developed by IEM Member Dr. Carston Wagner, Professor and Endowed Chair of Medicinal Chemistry and Director of the Chemical Biology Initiative. Dr. Wagner says the treatment can be used against a variety of cancers including those of the prostate, breast, pancreas, lung and brain, in addition to some types of leukemia. Unlike other immunotherapies in which cells are genetically modified, Dr. Wagner's technology uses a protein design - a chemical and biological approach of engineering the cells, which allows the treatment to be delivered to the patient in an "off-the-shelf" fashion, so that it can be given "much more readily." The treatment is currently in pre-clinical studies and is on track to proceed to a Phase 1 human clinical trial within two years.

This research had previously been supported by IEM seed funding, which Dr. Lim says, "supported the formation of an interdisciplinary faculty group of clinicians, engineers and neuroscientists that helped us refine our ideas and strategies for using noninvasive neuromodulation to therapeutically alter brain networks."
09/29/15 - Jay Kokate Featured in Star Tribune for Innovative Stent
IEM Industrial Fellow Dr. Jay Kokate was featured in the Star Tribune for his work in developing Boston Scientific's Eluvia stent to treat peripheral artery disease (PAD), a condition that affects more than 200 million people, globally. The stent, which could ultimately help prevent the amputations of the legs and feet of many diabetic patients, is coated with the drug paclitaxel, which is combined with a polymer to allow for its slow release, to prevent the re-narrowing of vessels in which it is placed - a common issue with stents. "We wanted to make sure that it was a sustained release for at least six months to a year," says Dr. Kokate. That slow release is believed among people at Boston Scientific to be the reason that 94% of patients in a clinical trial of the Eluvia stent avoided having to return to the hospital to have their arteries reopened within nine months of having it implanted.

08/27/15 - Kelvin Lim's PTSD Research Published in JAMA
Research led by IEM Executive Committee Member Dr. Kelvin Lim was recently published in the Journal of the American Medical Association (JAMA). Dr. Lim is Professor and Vice Chair for Research in the Department of Psychiatry, and Drs. T.J. and Ella M. Arneson Land-Grant Chair in Human Behavior. The randomized clinical trial, entitled “Meditation Interventions for Treatment of PTSD in Veterans," compared the effectiveness of Mindfulness-Based Stress Reduction, a group program that teaches participants to increase their mindfulness, "moment-to-moment, non-judgmental awareness," versus present-centered group therapy, in which participants focus upon their current life problems. The results showed that the Mindfulness-Based Stress Reduction was more effective than present-centered group therapy and comparable to standard therapies such as prolonged exposure. The Veterans Administration supported this research as part of its efforts to address posttraumatic stress disorder (PTSD), which affects 23% of veterans returning from the wars in Iraq and Afghanistan.

07/27/15 - University's Medical School Utilizing 3-D Printing to Produce Models of Body Parts for the Training of Students
As reported by the Star Tribune, the University of Minnesota's Medical School is using 3-D printers from Twin Cities-based Stratasys to make 3-D models of human body parts to train medical students, part of an increasing application of 3-D printing in medicine. IEM Member Dr. Robert M. Sweet, Associate Professor of Urology and Director of the university's Center for Research in Education and Simulation Technologies (CREST), is using 3-D printouts of kidneys to train students at the University of Minnesota and other institutions, including hospitals, nursing schools and military medical training facilities. In addition to producing models of organs, the printers are used to replicate a patient's specific anatomy in preparation for surgery.
The Department of Defense has partnered with the University of Minnesota and Stratasys to produce realistic head, tongue and trachea models in which the 3-D-printed body parts are further enhanced with silicone molds, hand-painting and water sealants, making them more realistic for the training of Army physicians and first responders. The tracheas, in particular, are realistic enough to be sold on the open market.

07/27/15 - Andrew Grande Discusses Need for a Greater Percentage of Minnesota Stroke Patients to Receive Recommended Treatment
In a recent Star Tribune article, Dr. Andrew W. Grande, Assistant Professor of Neurosurgery and IEM Member, discusses the need to increase the percentage of stroke patients receiving recommended treatment in Minnesota beyond its current level of 4%. Dr. Grande says that key factors in improving this figure are for patients to learn about the symptoms of a stroke, and then to seek immediate treatment at a hospital. That treatment, which has been primarily in the form of IV medications, will now include more medical devices that mechanically remove blood clots from patients experiencing acute severe strokes. So far, two devices have been approved for treatment of this condition in the U.S., one manufactured by Medtronic, and the other by Stryker. Early intervention is required, as current devices need to be used within several hours of the onset of symptoms.

06/29/15 - Clinical Trial Results Announced for Sleeping Beauty System
On June 21, 2015, results were announced of a clinical drug trial made with the gene-transfer method "Sleeping Beauty System" developed by the University of Minnesota's Dr. Perry Hackett, Ph.D., Professor of Genetics, Cell Biology and Development, and IEM Member. In the trial, half of the 16 patients treated with the cancer-killing CAR-T drug following bone-marrow transplant survived. The promise of this technology led to an investment earlier this year by drug company Merck of nearly $1 Billion, in addition to royalties. The Sleeping Beauty system, which is based on a transposon gene, is thought to be advantageous compared to other, virus-based methods of making CAR-T drugs, which can be more prone to mutations in the host DNA. As a result, the Sleeping Beauty system may be a faster, less expensive and potentially safer production method.

04/27/15 - Casim Sarkar Awarded 5-Year NIH R01 Grant
Dr. Casim Sarkar, Associate Professor of Biomedical Engineering, and IEM member has recently been awarded a 5-year R01 grant from the National Institute of General Medical Sciences of NIH, to study the interplay between noise and signaling in cellular decision making, with a focus on cell differentiation. At the molecular level, noise arises from inherent stochasticity in underlying biochemical reactions or variability in cellular machinery. However, it is still unclear how this noise propagates through signaling pathways to influence the trajectory of cell differentiation. Dr. Sarkar’s lab will use computational and synthetic biology approaches to elucidate how such trajectories arise and will use systems biology approaches to experimentally demonstrate and manipulate these trajectories in the differentiation of progenitor cells. The results of this study will yield deeper insights into fundamental mechanisms underlying cellular decision-making and should enable more robust engineering of stem and progenitor cells for applications in regenerative medicine.

03/26/15 - Killing Cancer at the Nanoparticle Level
Dr. Jayanth Panyam, Associate Professor of Pharmaceutics and IEM member, was featured in the American Society for Mechanical Engineers (ASME) News for his work in nanoengineering, and a method he has been developing for treating lung cancer with the use of nanoparticles. Dr. Panyam’s research shows an alternative way to manage lung cancer that does not involve chemotherapy, radiation, or a lobectomy. This treatment revolves around the use of an inhaler and magnets and results in attacking the surface of the tumor. First, the patient’s inhale the superparamagnetic iron oxide nanoparticles into their lungs. Next, the lungs heat up due to the surrounding oscillating magnetic field. By localizing particles in or next to tumor cells and then heating them up, the tumor cells die. Dr. Panyam’s study noted nanoparticles would likely attach to peptides that would then attach onto tumors. Dr. Panyam’s lab is currently working on creating a protein cocktail that would help the nanoparticles travel through the tumor matrix to attack the tumor from the inside.

03/26/15 - A More Precise Diagnosis for Oral Cancer
Dr. Curtis Corum, Assistant Professor of Radiology at the Center for Magnetic Resonance Research and IEM member, spoke to Health Talk in regards to a new technique named Multi-Band SWIFT (MB-SWIFT) which allows for the better identification of oral cancer in the jawbone. Unlike previous techniques of oral cancer identification such as CT scans and clinical examinations, MB-SWIFT makes it much easier to see if cancer has reached the jaw by providing sharper images and brightening cortical bone. This new technique makes it possible for clinicians to forgo unnecessary procedures such as a biopsy or surgery to determine if the cancer has reached the jawbone. The future of this technique is the hopeful continued translation of this form of oral cancer diagnosis and making it more widely available to patients and their doctors.

02/26/15 - Daily Low-Dose Aspirin for Heart Attack Prevention
Dr. Alan T. Hirsch, Professor of Medicine, Director of the University of Minnesota’s Vascular Medicine Program, and IEM Member, is leading a study that aims to minimize the rate of stroke and heart attack in groups of people that are of moderate to high risk–men age 45 to 79 and women age 55 to 79.
The result of a trial version of this study was that the proportion of the people in the targeted population who took a low-dose aspirin rose from 36 percent to 54 percent in four months, helping them better manage their health. In article recent article published in the StarTribune, Dr. Hirsch explains that this was a higher percentage increase than expected, and that if this same pattern could be achieved statewide, as many as 7,000 first heart attacks and strokes a year could be prevented over the next five years. Dr. Hirsch also emphasized the importance of individuals to first determine with their doctor if they have the right heart risk rate and the lowest bleeding risk before committing to the program.

12/29/14 - Ask Patients to Consider Aspirin Use
The Minnesota Heart Health Program is working to reduce heart attacks and strokes in Minnesota through a campaign called “Ask About Aspirin”. Dr. Alan Hirsch, IEM Member and Professor of Medicine, commented on the program in an article by the St. Cloud Times. The program trains health care professions in the appropriate use of aspirin and aims to increase awareness of the benefits of regular low-dose aspirin use to reduce the risk of heart attack and stroke among those who have the greatest risk; women aged 55 – 76 and men aged 45-79.
In the article Dr. Hirsch explains how much easier it is for adult patients to take 81 milligrams of aspirin per day as compared to the other recommended risk reductions: losing weight, quitting smoking, and taking a statin for cholesterol. There is also a higher percentage of reduction risk by taking an aspirin than compared to the other methods. The campaign’s aim is to encourage patients to discuss aspirin with their physicians and to encourage physicians to consider recommending aspirin to help prevent heart attacks and strokes in their patients.This campaign is sponsored by the Lillehei Heart Institute and University of Minnesota School of Public Health.

A team from the University of Minnesota led by Prof. Jian-Ping Wang, IEM Member and Professor of Electrical and Computer Engineering, has been selected as one of five Distinguished Award Prize winners, valued at $120,000, at the 2014 Nokia Sensing XCHALLENGE, a global competition to develop breakthrough medical sensing technologies that will ultimately enable faster diagnoses and easier personal health monitoring.
The Golden Gopher Magnetic Biosensing Team developed a handheld device, named “Z-Lab,” designed to detect various ailments using indicators, or biomarkers, found in bodily fluids at the earliest stages of disease, often when symptoms are not even present. A drop of fluid is placed on a small biochip (~10 millimeters by 10 millimeters). Results of up to 10 health indicators are displayed within 15 minutes on a smartphone, tablet, or other mobile device. The sensor can also be used for monitoring other factors that can impact one’s health, such as the mercury concentration in water.
“The high sensitivity of this device allows it to detect various ailments—including infections, heart disease and even cancer—faster, easier and earlier than ever before,” said Dr. Wang. “We see this as a prevention-based device that will ultimately save lives.”
The Team includes professors and students from the University of Minnesota, doctors from the Mayo Clinic and engineers from several corporate partners, including Zepto Life Technology, a University startup company commercializing this technology.

11/25/14 - Kalpna Gupta's Work on Pain in SCD Highlighted in Nature Outlook
Pain is one of the most debilitating outcomes of sickle cell disease (SCD). Individuals with SCD can suffer with chronic pain and unpredictable intermittent pain throughout life. Even though pain in SCD is difficult to treat and requires high dose of opioids and hospitalization, its mechanisms remained unknown. IEM member and Co-Chair of Cellular and Molecular Bioengineering Theme, and Professor of Medicine, Dr. Kalpna Gupta started examining the mechanisms of this pain few years ago.
In a recent issue of Nature Highlights (Sickle cell disease, Nature Vol 515, No. 7526_supp ppS1-S49) Gupta’s work is highlighted for its contribution to understanding the mechanisms of pain and why higher doses of opioids are required. In the article, “Life Beyond the pain” it says, “Another of Gupta’s findings may help to explain why the effects of opioid drugs fade so quickly for people with sickle cell, and why they need higher doses than people with other conditions who have similar levels of pain. Nerves in the skin and spinal cords of the sickle-cell mice showed a reduced level of the μ-opioid receptor, which enables opioid painkillers such as morphine to take effect.” Accompanying figures in the article show abnormalities in peripheral nerve fibers in the skin of sickle mice that may contribute to chronic pain in SCD. These studies laid down the foundation of pain research in SCD.

10/27/14 - Pulse Oximetry Screening –Testing that Saves Lives
IEM Member and Associate Professor of Pediatrics, Dr. Lazaros Kochilas, created a pilot study in six hospitals to see how easily a test could be implemented that could save the lives of newborns in Minnesota. Recently featured on WCCO TV, Dr. Kochilas’ study began in the aftermath of informing a Minnesota family, the Saarinens, about a murmur that was detected in their seemingly healthy baby daughter due to a heart defect. This simple screening done before discharging a newborn is noninvasive, takes less than a minute, but is sometimes not performed by physicians.
After her daughter’s recovery in the wake of a successful emergency surgery the child’s mother, Annamarie Saarinen was an advocate for change. She brought an idea of using pulse oximetry screening to screen all newborns to her daughter’s doctor, Dr. Kochilas. His study has led to a new state law that requires Minnesota hospitals to use the pulse oximetry screening test to screen every newborn before they are discharged.

08/29/14 - Pioneering Treatment for Epidermolysis Bullosa
Dr. Jakub Tolar, IEM Member and Director of Stem Cell Institute, and Pediatric Blood and Marrow Transplant Physician at the University of Minnesota, recently had his pioneered treatment methods for Epidermolysis bullosa (EB) featured by NBC News. EB, a genetic disorder which prevents skin layers from attaching properly causes patients to have painful lesions, blisters, and sections of skin subject to constant detachment from the body. Ranging from mild to severe there are thought to be approximately 25,000 to 50,000 people living in the United States with EB today. The clinical trial and study led by Dr. Tolar focuses on treating EB by replacing the bone marrow from healthy persons which heals the symptoms of EB.
Untreated, EB will lead to painful disfigurement and in most cases an early death before the age of 30. Before Dr. Tolar’s study, treatment methods that would change the outcome of EB patients were not available. Dr. Tolar’s study and clinical trials are still experimental, but the treatment method he has pioneered has been the treatment of choice by patients with the most severe cases of EB.

08/29/14 - The Neuroscience of Football
Dr. David Redish, IEM Member and Distinguished McKnight Professor of Neuroscience recently sat down with Sports Illustrated to shed light on how truly complex it is for football players to master the playbook, on a neurologic level -- “It’s like trying to play a musical instrument that’s scheming against you.”
What Dr. Redish explains in the article is that not only do players need to memorize hundreds of distinct plays, but also to translate that memorization into the correct action, sometimes with only seconds of warning, a process called consolidation. In addition, players need to perpetually anticipate plays the opposite team is attempting to conceal, all while working to elude the other team from anticipating their team’s moves. Dr. Redish explains that the decision-making of the procedural system is located in different parts of the brain which can account for some of this complexity. “Memorization can only take a player so far during game situations.”

06/30/14 - How to Help Stroke Victims F.A.S.T.
Dr. Andrew Grande, IEM Member and Assistant Professor of Neurosurgery, emphasizes the life-saving importance of quick action when you notice someone who shows the signs and symptoms of a stroke. The key is to act F.A.S.T. As Dr. Grande explains in a YouTube video created by the University of Minnesotas Academic Health Center, F.A.S.T stands for: Face drooping, Arm weakness, Speech difficulty or slurring of words, and the action you need to take when you notice these symptoms — Time to call 911 and get the victim to the hospital.
In the video Dr. Grande stresses the importance of recognizing the symptoms and of taking action because the only thing that we can do for someone who is having a stroke is to reopen the blood vessels and we need to do that fast, within three hours of when the symptoms first occur. Dr. Grande advises to call 911 immediately if you see signs that indicate someone may be having a stroke.

04/02/2014 – Hubert Lim Receives NIH U01 Grant for a New Hearing Prosthesis
IEM Member Hubert Lim, Ph.D., is an Assistant Professor in Biomedical Engineering, adjunct faculty in Otolaryngology, Head and Neck Surgery, and an Institute for Translational Neuroscience Scholar. He was recently awarded a 5-year U01 grant from the National Institute on Deafness and Other Communication Disorders to perform a Phase I clinical study testing the safety and efficacy of a new deep brain stimulation array for hearing restoration, known as the auditory midbrain implant (AMI).
The project is an international collaboration with leading clinicians and researchers from Hannover Medical University in Germany (led by Co-PI Thomas Lenarz, Chair of Otorhinolaryngology) and scientists and engineers from Cochlear Limited in Australia (led by Co-PI James Patrick, Chief Scientist & Senior Vice President).
For the past 10 years, Dr. Lim and colleagues have developed new deep brain stimulation technologies for restoring hearing in deaf patients who cannot benefit from the standard cochlear implant. Through a series of animal and cadaver studies, they obtained sufficient data and approvals to implant five patients during 2006-2008 with the first generation AMI device, which consists of 20 electrodes along a single shank that is implanted into the main auditory region of the midbrain. Although the initial results were encouraging in the ability of the AMI to restore useful hearing on a daily basis, the performance levels had not yet reached those of the cochlear implant. Through further research in animals and the five AMI subjects, a second generation AMI device was developed that consists of two shanks with a total of 22 electrodes.
In addition to the large number of sites, this AMI device has a fast processor, high stimulation rates, current steering options, multi-site neural recording capabilities, and a wireless interface. Five patients will be implanted with this new AMI device from 2014-2016 and evaluated over a two-year period to demonstrate the safety of the AMI and its improved function compared to the first generation device. The success of this project will lead to a larger clinical study across multiple implant centers worldwide to justify its use as a standard hearing alternative for those who cannot sufficiently benefit from a cochlear implant. This AMI technology can potentially be used for other deep brain stimulation and clinical applications.

04/02/2014 – Dr. David R. Jacobs’ Study shows how the Brain Benefits from Good Heart Health
IEM Member and Professor of Epidemiology, Dr. David R. Jacobs, recently spoke with NBC news about a study he designed and led showing the correlation between fitness levels of individuals in their 20’s to their mental fitness levels twenty-five years later. Dr. Jacobs and his colleagues found that one who is physically fit at a younger age is more likely to have better mental fitness in middle age. The study began with the administration of a treadmill test in 1985 to a group of around 5,000 people. Of that group, around 2,700 took the treadmill test again in their middle age. Five years after the most recent treadmill test the study participants underwent three different kinds of memory tests. Dr. Jacobs and his colleagues found that those who received a high score on the 1985 treadmill test also received a high score on the memory tests in middle age.
This study, published in the Journal of Neurology, illustrates the benefits of brain health through good heart health. Dr. Jacobs encourages people to actively engage in life as this has been shown to better preserve brain function.

04/02/2014 – Thawing the Freezing of Gate in Parkinson’s disease Patients
Over half of all who are diagnosed with Parkinson’s disease also experience terrifying and debilitating episodes of ‘freezing of gait’. Whether these episodes of inability to begin or continue walking forward are frequent or not it is continually frustrating and potentially dangerous to the patient. Current treatment options for these episodes include Dopamine replacement therapy and the presentation of visual cues or signals that have been shown to break up the freezing episode.
Using high-speed cameras and electronic sensors Dr. Colum MacKinnon, IEM Member and Assistant Professor in the Department of Neurology, is working to uncover the source of why some visual cues work and others do not. Dr. MacKinnon is researching new methods and strategies of how to present visual cues in order to allow patients to overcome or avoid the ‘freezing of gait’ altogether, and to better design more reliable treatments to release Parkinson’s disease patients from their episodes of immobility.
04/02/2014 – Methods of Cancer Vaccines
A vaccine to treat canine brain and bone cancers using the canine’s own tumor cells, a method originated with Dr. Elizabeth Pluhar, IEM Member and Associate Professor of Veterinary Clinical Sciences, and immunologist Dr. John Ohlfest, was recently featured on an Australian Show called Bench to Bedside, and featured in a story on KARE11 and by University News.
In their research Dr. Pluhar and Dr. Ohlfest came up with the idea to maintain the same low-oxygen environment for cells as the tumors themselves grow in. This made the cells seem less artificial to the immune system. This insight led the FDA to give the research accelerated approval to test on humans.

03/31/2014 - IEM Members Awarded Minnesota Partnership Grants for Collaboration with Mayo Clinic
IEM members John Bischof and Raj Rajamani and their colleagues received grants from the Minnesota Partnership for Biotechnology and Medical Genomics, a collaboration among the University of Minnesota, Mayo Clinic and the state of Minnesota.
John Bischof, Ph.D., IEM Associate Director for Development and Professor of Mechanical and Biomedical Engineering, is PI of a recently awarded Minnesota Partnership grant of $578,339 to develop a series of laser prototypes that can be used to enhance rapid diagnostic tests for malaria. Still a problem around the world, malaria cases have dropped by nearly a third in the last decade thanks to rapid diagnostic tests. But those tests, while fast, are not sensitive enough to detect lower levels of malaria or all strains of the disease. The goal of this project is to develop a series of laser prototypes that can be used to enhance rapid diagnostic tests for malaria. The laser work will be done at the University of Minnesota and a new reference lab measurement technique will be developed at Mayo Clinic. Other team members include Bobbi Pritt, M.D., the PI at Mayo Clinic and David Boulware, IEM Member, Assistant Professor of Medicine and the Co-PI of the project at the University of Minnesota.
Raj Rajamani, PhD, IEM member and Professor of Mechanical Engineering, together with Mayo Co-PI Bruce Johnson received a new Minnesota Partnership grant of $559,777 to develop smart socks tracking heart failure. The feet offer telltale symptoms of heart failure and obesity. These researchers will be developing and testing a pair of sensor-socks that people at risk for problems can wear so physicians can monitor subtle changes in body weight, water gain, edema and variations in heart rate. The goal is to have a marketable product that will detect early signs of trouble and prevent heart attacks before they happen. The University is engineering the socks; Mayo will do the physiological tests.

03/31/2014 - Jianyi Zhang Awarded NIH R01 Grant to Investigate Myocardial Repair
Jianyi (Jay) Zhang, MD, Ph.D., IEM Cardiovascular Engineering Theme Co-Chair and Professor of Medicine, was recently awarded a new R01 grant of $1.95 million from the NIH, National Heart, Lung, and Blood Institute to investigate myocardial repair using human iPS cells derived trilineage cardiac cells.
The R01 grant proposal, based upon pilot data supported in part by an IEM group grant, received score of 1.0 and 1 percentile, will enable Prof. Zhang and his team to examine myocardial ATP turnover rate of in vivo heart in a super high field large bore magnet with previously unattainable levels of sensitivity and spatial localization. The set of experiments seeks to develop a "human cardiac muscle patch (hcMP)", formed by entrapping human cardiac myocytes (CM), endothelial cells (EC) and smooth muscle cells (SMC) that derived from patient specific induced pluripotent stem cells (hiPSC) in a modified 3D porous fibrin biomaterial. Using a porcine model of postinfarction LV remodeling, this research project will examine whether the transplantation of a prefabricated hcMP could result in better functional outcomes in reductions in LV scar bulging and wall stress, and improvements in myocardial, perfusion, bioenergetics and contractile function. The success of this project will enable identify methods to be readily applied in a clinical setting and, consequently, provide an entirely new and valuable method for treatment and monitoring myocardial function, metabolism, and perfusion in the human heart.
03/31/2014 - Daniel Duprez Speaks to WCCO 4 News on the Importance of Heart Screenings of Patients in their 30’s
Daniel Duprez M.D., Ph.D., IEM Member and Professor of Medicine, was featured in an article and news piece by WCCO 4 News in which he discussed the importance of people as young as 30 receiving heart screenings in order to prevent a heart attack.
These heart screenings consist of a series of nine tests and a blood draw and are done by the University of Minnesota Rasmussen Center. A Blood Pressure test is administered along with other tests such as a special heart rate test, an exam to monitor the blood vessels in the eye, an ultrasound to check the arteries and the heart, and a written enjoyment of life scan, among others. Each patient receives immediate feedback after each test is complete and also receives a complete analysis and personalized heath plan at the conclusion of the screening.
This heart screening is done to anticipate and manage heart and artery disease by checking for early markers of cardiovascular risk. Prevention is key, because as Dr. Duprez stated, once you have a heart attack, the damage is done.

01/29/2014 - NIH R01 Grant Awarded to Sachs Research Group
A seed grant from the Institute for Engineering in Medicine (IEM) assisted in funding the research of Dr. Jonathan Sachs, Associate Professor of Biomedical Engineering and IEM member, to study the protein α-Synuclein. The Sachs Research Group was recently awarded an NIH R01 Grant to study this protein. Dr. Sachs’ laboratory studies the protein α-Synuclein, whose aggregation into insoluble Lewy bodies is commonly associated with Parkinson’s disease (PD). While the connection between α-Synuclein and PD has been recognized for some time, the normal function of αS remains a mystery. The goal of Sachs Research Groupis to develop a mechanistic understanding of the inhibition of synaptic vesicle fusion by α-Synuclein. A precise understanding of the native interactions between α-Synuclein and synaptic vesicle membranes will position the Sachs Research Group to evaluate the protein’s role in vesicle trafficking defects as they relate to PD. Their approach involves quantitative studies of the biophysical and mechanical properties of synaptic vesicle membranes. The lab will combine state-of-the-art computational molecular simulations (utilizing the highly powerful machines in the Minnesota Supercomputer Institute) with a panel of complementary biophysical experiments (including atomic force microscopy—to be performed at the University’s Characterization Facility). Led by a brilliant graduate student, Anthony Braun, the lab aims to establish the foundation for new therapeutic strategies in the treatment of PD, namely to exploit the native function of the protein (i.e., restoring proper vesicle trafficking).

01/29/2014 - David Odde recieves National Cancer Institute R01 Grant
David Odde, Ph.D., IEM Cellular and Molecular Bioengineering Theme Co-Chair and Professor of Biomedical Engineering, was recently awarded a new R01 grant from the National Cancer Institute to develop an integrated modeling and microsystems approach to glioma invasion. The $2.3M grant will involve researchers from Neurosurgery, the Masonic Cancer Center, the College of Science & Engineering and a collaboration with the Cleveland Clinic. A major goal will be to develop a "flight simulator" to simulate the mechanics of brain cancer cell migration in the brain, and use the simulator to identify possible therapeutic targets. In this study, Prof. Odde and colleagues will be using a combination of advanced genetics, mouse models, and confocal light microscopy imaging to quantitatively measure glioma cell migration and force generation dynamics in live mouse brain slices. In parallel, they are developing advanced in vitro systems with controlled chemical and mechanical properties that more closely mimic normal and diseased brain tissue. Finally, these advanced experimental systems will be used to develop the "flight simulator" for the migrating cancer cells. This computer model will then be used to screen in silico for the most vulnerable nodes, and node combinations, in the mechanochemical network. Ultimately, they hope to find drug target combinations that strongly and selectively disable glioma cell migration, leading to new and more effective therapies. David Odde Laboratory>

01/29/2014 - The Black Bear Hibernation and Heart Health in Humans
Dr. Paul Iaizzo, Professor of Surgery, IEM Associate Director, and Director of the Visible Heart Lab, was recently interviewed by KSTP to discuss his black bear research and its possible translation to human heart health. Dr. Iaizzo explained that during hibernation the heart rate of a black bear significantly increases during inhalation and drops to only a few breathes per minute during exhalation. This adaptive cardiac physiology may have broad implications for human medicine and possibly space travel, since it would allow for prolonged periods of inactivity while maintaining both cardiac capacity and alertness. NASA has shown interest in the research. Read more through Minnesota Black Bear Research and KSTP-TV>
12/31/2013 - Giant Magnet Makes U Attractive to Brain Mapping Researchers
The world’s strongest imaging magnet has arrived at the University of Minnesota after being delayed more than a year. The Siemens MAGNETOM 10.5T will aid in brain research as part of the University’s new addition to the Medical School’s Center for Magnetic Resonance Research (CMRR). A global shortage of helium delayed the arrival of the magnet, which uses the element for cooling. “Researchers will use the magnet primarily for brain activity and human body imaging,” said Kamil Ugurbil, CMRR director and IEM member, “Being able to image human brain function improves significantly with magnetic field.” The higher magnetic field will likely provide better imaging of the human body and extremities as well, he said, although they’re much trickier to work with in a high magnetic field. CMRR received an $8 million grant from the National Institutes of Health and millions from the University for the magnet project. Read the full article through StarTribune, MPR News or KSTP TV Video>

11/30/2013 - Minnesota to Resume Umbilical Cord Blood Donations, Jeffrey McCullough Quoted in Star Tribune and MPR
“Fact is, this is the world’s largest cord blood transplant program,” said Dr. Jeff McCullough, a U pathologist and specialist in transfusion medicine quoted in Star Tribune. “To not even be collecting here for potential transplants? We should be able to do better than that.” This November, the medical center ironed out plans for an umbilical cord blood donation program to save stem cell researchers money and make the donation process easier. Laboratory medicine and pathology professor Jeffrey McCullough said the proposed deal, which would link the University with Fairview Health Services’ Riverside clinic and the St. Louis Cord Blood Bank, would give the University more access to stem cells at no cost. He said the plans are exciting because the University currently has to buy these stem cells from a cord blood bank at a great expense. Umbilical cord blood is in demand because it contains stem cells used in a variety of medical procedures, including the treatment of cancer, McCullough said. He also said that researchers could look into making the cord blood stem cells into tissues that adult marrow stem cells cannot produce, like cartilage and heart muscles. The deal is expected to be finalized once official contracts are written by the blood bank and signed by Fairview’s attorneys. Read the full article>
11/30/2013 - U of MN’s Project Stealth Attacks Cancer in a New Way
Daniel Saltzman, M.D., an IEM Member, led a team of researchers who working on the University’s Project Stealth have altered salmonella so it no longer causes food-related illness, but rather, delivers cancer drugs interleukin-2 (IL-2) and other proteins like IL-15 to tumor cells. Once there, they work to stimulate the patient’s immune system to destroy cancer cells. Saltzman is quoted in Health Talk, the University of Minnesota’s health news blog. The key, Saltzman says, was the discovery that salmonella naturally flocks to tumor cells. Knowing this, researchers can use the bacteria to their advantage, attacking tumors in a new way. “It’s a completely nontoxic way of treating cancer that involves boosting the immune system and changing the microenvironment of tumors, rendering them nonresistant to various therapies,” Saltzman said. To raise awareness about the project, Saltzman took a non-conventional route, seeking funding from philanthropic donors and organizations rather than the traditional government or University grant funding. He hopes a new advertising campaign, provided free of charge by a local advertising agency, will help raise awareness and push Project Stealth to a point where large funding groups and the NIH will take notice.

11/30/2013 - David Wood Receives American Heart Association Scientist Development Grant
David Wood, Assistant Professor of Biomedical Engineering and IEM Member, received the Scientist Development Grant from the American Heart Association in Self-assembled 3D vascularized tissues. He is working to address a fundamental problem in tissue engineering, which is the ability to engineer an in vitro vascular network that can supply nutrients and oxygen to cells within artificial tissues to maintain viability and function. The goal is to self-assemble a vascularized tissue construct from cell-laden micro-scale hydrogels, using only macroscopic parameters to control the self-assembly process in a highly scalable fashion. The anticipated result will be a method for producing vascularized tissue constructs in vitro that will match the efficiency of vasculature in vivo and which is scalable to arbitrarily large tissues. This method promises to greatly expand the range of applications for artificial tissues, including transplantable constructs, physiologically relevant disease models, and in vitro pharmacokinetic platforms to develop new therapeutics. Dr. Wood is a recipient of IEM Exploratory Grant in the past year.

09/30/2013 - IEM Member Bob Tranquillo featured in Star Tribune Article, “Using Human Cells, U Professor Builds Circulatory System Fixes”
Dr. Tranquillo, member of the Institute of Engineering in Medicine, and head of the Department of Biomedical Engineering at the University of Minnesota works tirelessly in his lab with a team of researchers on creating arteries and heart valves manufactured from human tissue. Processes developed in his lab, which Dr. Tranquillo has been refining over the last 20 years, addresses many of the major issues with current replacement valves. For example, patients currently require multiple follow-up visits to control their body's responce to the tissue. Valves available today also do not have long-term use, as they only last about 10-15 years before they wear out. Also, with current market solutions, children are particularly vulnerable to valve replacement procedures — current valves do not grow as they get older, requireing multiple invasive surgeries to help them moderate their conditions. Recently highlighted in an article in the Star Tribune, Dr. Tranquillo spoke about the impact his work has for the public stating, “From one person’s donation of skin you could probably have enough cells to treat thousands of patients.” Through recent advances in his lab, he and his team are at the critical point of a medical breakthrough. They are nearing a process where engineered valves will actually regenerate tissue, instead of leaving a surgical scar. Read the full article>

08/28/2013 - IEM Member Dr. Talkachova Receives NSF CAREER Award
Dr. Alena Talkachova, Assistant Professor of Biomedical Engineering and IEM Member, recently received a CAREER award from NSF for her research on “The effect of feedback on cardiac dynamics”. This project studies the natural phenomenon of electrical restitution in hearts, which is characterized by a shortening of the action potential duration of a heart as the heart rate increases. For the past several decades, mathematical modeling of electrical restitution received a lot of attention; however the current theory of electrical restitution was developed for periodic stimulation only. However, in the heart, the heart rate is never periodic, thus leading to the presence of the heart rate variability (HRV), which is modulated by many physiological factors, including the influence of circadian rhythms, temperature regulations, changes in cardiac sympathetic and parasympathetic nerve activity, respiratory rhythms, etc. The main goals of the proposed research are to extend the concept of electrical restitution to the case of non-periodic physiological stimulation by including HRV, and to develop a new algorithm for pacemakers that provide antiarrhythmic effect to the heart by stabilizing cardiac rhythms.
08/28/2013 - IEM Member Dr. Papanikolopoulos’ Scout Robot Highlighted in Big Ten Network Video Series

05/29/2012 - Parhi receives IEEE Circuits and Systems Society Award
Dr. Keshab Parhi, IEM member and Electrical and Computer Engineering faculty, received the IEEE Charles A. Desoer Technical Achievement Award, which honors the individual with exceptional technical contributions to a field within the scope of the IEEE Circuits and Systems Society. The award is based on contributions as documented by publications (including but not limited to patents) and based on originality and continuity of effort. Dr. Parhi has developed a systematic theory of high-level transformations for iterative data-flow graphs. These graphs are used to describe signal processing algorithms. Architectures that are derived from these transformations lead to integrated circuits that can be used in very high-speed and low-power applications such as a gigabit Ethernet, a 10-gigabit Ethernet, or optical fiber transmission systems. Other transformations lead to integrated circuits that are used in cable modems and set top box applications. Dr. Parhi is currently working on the design of low-power biomedical devices.
